As far as go fast parts I think that's where I'll probably leave off, maybe I could drop to a 3.6 pulley or some minor thing like that once I can tune.

Depending on if you want to change the valve springs or not, you can run up to 1.84:1 Roller's with the stock springs; even though I still recommened at LEAST G8 (L76) Springs/Retainers...keeping the stock pulley would probably be ideal with the PLOG/DP setup...and just buy a Wideband and have it custom tuned (maybe run up the shifts to 6K, but that would be ideal)...run a little leaner, and toss some extra timing at it. You could also pull the "it's still stock" card as well

Probably make a solid 230~ FWHP, good for low 14's on a good day if not quicker with some sub 2.0 60's...I loved my 3.29 gearing...yay Comp G.

I like the small suttle additions, like the Comp G badge on the dash...clean choice of wheels and tips as well, car looks like it was very well taken care of.

Now she just needs some tint

awesome car dude, double din radios are better tho =D

No pics of more than half the car ?

Needs some tint too!

Looks clean, enjoy it!!

Car looks really good. Love the rims.
Ditto on the tint.

Your leak might be from the onstar antenna... If you get a drip from your map lights its a leak there for sure... common on our cars..

BTW welcome to the world of the Comp G.

I hope you enjoy yours as much as I enjoy mine.

ohh limited warranty ?

he owns a dealer ship?!? wow he's lucky and so are you lol. he probably makes $$$

lol my friend owns a dealership luckiest kid around here. he get to drive whatever he wants. he hooked me up with my GTP for $1600 with 116k on it

pwn.

Got my Aeroforce gauge in, installed it in the vent today. It's definitely cool, still learning how to use it. When I first plugged it in, I took the car for a ride, I had it set to KR and Ign Advance... and I just pulled out from my curb, stopped at my stop sign, then I pulled out pretty gently up the street, only 15mph speed limit... and the KR flew up to 20*... I was like wtf is this. I've got plog and 3" downpipe with an intake and stock pulley, stock tune. After I drove for a few minutes though, I looked at it again and it was reading zero.

Took it out a little while later and watched it on some pulls, on 70% throttle KR stayed zero until right before the 2-3 shift where it jumped to 2* for a second and went back down to like .3 then to zero. It's working well now, dont know what that 20* thing was about though. I definitely love some of the functions it has... I got Overkill pcm on the way, hopefully that'll go in 2 weeks from now since he's on vacation.

Just popped the vent assembly out, popped the ball retainer out, ball falls out easy, need a 60mm CordAway grommet that you can get at Staples, the gauge fits very snug in the grommet... wrap electrical tape around the outside of the grommet until it fits very tightly into the hole where the vent ball used to be.

Drop the OBDII wire back behind the kick panel below the steering wheel to the OBDII port, then I just wrapped the slack of the wire up into a tight loop and fastened it there with a zip tie. Block off that vent by cramming a towel or something in there, you dont want red hot air, or ice cold AC blasting on it. Bolt it all back up and be happy.

Yeah, that 20* KR had to be false. Wouldn't the car shut off if all the timing was pulled?

Had a detail day today and yesterday. First one in awhile since it's been raining every other day for almost 2 weeks, I ususally try to keep it up every other week in the summer.

Wash, dry, wax, black the tires and polish the wheels yesterday. Today I went over the whole car with Meguiar's Ultimate Detailer for the last touch of reflectivity and deepness. Cleaned and conditioned all the leather seats, shift knob, and steering wheel. Definitely wanna do the engine bay soon.

I wanna throw an inferno hood on this with the SE Lip, get the blower polished with a full engine bay detail and enter some shows next year if I have it done in time













Aeroforce, shiny leather!

But the car looks AMAZING!!! Good job

ahhhh so clean. looks awesome.

Freshly detailed cars are faster than dirty ones, and it's backed up my hard science.

You wash off all that dirt = weight reduction.

^Also reduces drag...so yea,true story.

So, after much waiting I finally got my Overkill tune. I love it, it's awesome. As some people have told me I think the most noticable change is in the shifting, it's great. 1-2 is crisp and firm all the time, but 2-3 and 3-4 seem to be more dependent on throttle. Light throttle and they're smooth as glass, cant even feel it shift, but when Im gettin in it it's so firm and quick, I love it! Downshifts and TCC lockup seem to be way way better too, I was having a problem in another thread with a total lack of power or response trying to come out of a cruising/coasting situation like going from downhill to flat or uphill, when I needed the throttle for uphill or flat and I put the gas down I'd have 0 response until I was so far into the throttle it kicked down to the next gear hard and took off like I floored it. Well new MAF and a sealed vac leak fixed it but it remained a tiny bit... but that's gone completely now. There's also no lag on downshifts anymore, when Im doin 30 and I hammer it.. it goes... not 1,2,3,4... GO.

Definitely got some extra pull through the whole rpm band and any KR I had before has been wiped out. MPG's remain unchanged. Tranny seems to run way cooler, like 30*, and having the fan on all the time above like 180* I think it's set at keeps the ECT very stable and in a nice range, even stopped in traffic. It's definitely a lot of fun to have, and I recommend it for anyone boosted or NA... just the shift settings are worth it. It might take forever to get it, but it makes it that much sweeter when you finally get it.

I read a suggestion from Matt to use Shell V-power so I filled up on it. Since I bought the car it was having a problem of hard starting, almost like it would cough and sputter and shake then start all in one turn of the key on the first start of the day. It was really rough and bothering me. Persisted even after I did the Seafoam induction and spark plugs... well 2 days of running the v-power and that problem suddenly stopped... I was amazed. Still hasnt come back after a week now. No increase in MPG's yet but reading around some people take a tank or 2 to see full benefits. The car might even have a little bit more pep now going from a stop and at low speed acceleration.

Also I've been doing some studying on motor oil with Bob Is the Oil Guy, after looking at all the numbers and analyses on so many different oils, I decided to go with 0w30 Amsoil Signature Series. Im going to be doing a 7-10k interval on a Bosch Distance Plus filter. I dont want to sound like another Amsoil nut hugger, but I really did feel a difference from Castrol Edge. The car starts even easier than it did with using the V-power gas, like it feels like it has to crank less and takes less effort. It just seems more eager to move, like I noticed the tiniest tap of the gas makes the car go forward more than it used to. Acceleration just feels smoother and the motor is actually quieter. I know some people might say placebo effect, but I started off on the critical side, paying very close attention to before and after and reminding myself to be realistic and neutral.

Reading on synthetics in general I find that a few years ago a legal battle between Castrol and Mobil 1 caused the definition of "synthetic" to change. Synthetic oil basically used to mean there was zero petroleum in it, base stocks were a chemical lubricant called PAO that's far superior to anything made from crude and costs a bundle more as well, oils made from PAO were classified as Group IV. Castrol found a way to further refine petroleum base stocks that were used to make conventional oil even further. It was refined to such a point that Castrol claimed it no longer resembled anything in nature and so it was technically synthetic... and though it was way cheaper and not quite as good a lubricant as PAO, it was deemed Group III, and Castrol continued to charge the premium price of PAO synthetics.

From what I read, most major name oil manufacturers on the market have switched over to this Group III based oil, while only a few have remained pure PAO, and Amsoil is one of them. I think this is a big part of why Amsoil used oil analyses come out with noticably better numbers on average, why they can safely advertise a 25k mile oil change interval under their 'standard' service recommendation.

Anyway, I figure the cost will balance out or even come out better for me, paying 60 bucks per oil change and only doing it like twice a year.. vs 35 bucks every 3k.

Sorry for the book, wanted to explain my thinking on that and why I think it's not just placebo, lol... there's my update.
