what should i spend $2k on for 98 gtp

**mskram1** · 06-03-2011

and im still not sure if i want to spring for a canned tune or actually get into tuning with dhp or something to that effect

**machinegunsquid** · 06-03-2011

Just get Reptile to port your stock L67 TB. He does great work.

Depending on the mods, an Overkill tune is okay. Start getting into ported Throttle bodys that skew the MAF readings, and you'll def want a live tune.

im gonna go look into the tuning thread... there may b some potential there

**mskram1** · 06-04-2011

ok so im definately getting hptuners pro, 3.3" pulley, aeroforce interceptor scan guage w/wideband add on, solid engine and trans mounts from zzp, some zzp wheel bearings, shorter dogbones from zzp... my big question is can i tune a stock pcm or do i have to buy an aftermarket one from zzp or overkill???

**matt5112** · 06-04-2011

shorter dogbones are the worst way to correct axle geometry.

Using trans/engine mount spacers is a better way.

**mskram1** · 06-04-2011

ok i actually custom fabbed some of my own spacers thanks for the tip

ZZP wheel bearings last a little over a year on my car before both went bad.

That's why ya get TIMKIN ones from Autozone

**mskram1** · 06-05-2011

timken it is... kinda needed to get my shipping costs down anyways

idk what i would do without everyone here. oh i kno id b driving a mustang or honda lol

**mskram1** · 06-05-2011

ok if i get wbody stores cnc heads w/1.9.1 rockers and a 3.4" pulley on my headered setup could i just tell reptile thats what im getting and he'll be able to make me a bad a tune for it??? or could i just get a canned tune... or a custom tune from overkill... i dont have the time to custom tune having kids and all... and if i do custom tune could i make enough power to rule out getting rockers???

**blueguy** · 06-05-2011

Honestly if you can't get a custom tune...then I would either...

A) Buy a Tuner...either an old school DHP or a HP Tuners Suite.

B) Don't mod your car past a basic 3.4" setup

**mskram1** · 06-06-2011

thats about the same conclusion i came to... probably gonna go have the cylinders pressure tested in a few days to see where i stand... not gonna get a tuner untill i decide to get a cam... just gonna go the safe route and use the 3.4 with a canned tune from overkill, an aeroforce w/wideband add-on (just to have it for the future mods)... zzp progress front and gmpp rear swaybars, zzp trailing arms, and the Fbody front brake upgrade the rear upgrade is a little pricey

why don't you just put the 2k aside for a year and see how the tranny holds up, and see how much more $ you will have next year. When modding, it never hurts to have funds set aside for a replacement tranny. Save up, put in a TEP next year with 3.29's and build around that (a cam would be a good idea to put in at the same time). Much more reliable that way since its a DD.

Also if the place can tune an LS1, it probably can tune a GTP. So I would see where the F bodies and corvettes go in your area for a tune.

You'd think so, but I called like the only dyno tuner in town and he pretty well flat out told me he only does ls motors and wouldn't even touch my car... I really just needed to get it halfway close at that point and I told him that and he told me to call some shops in dallas lol

Either he's an LS snob, or a cheap bastard and doesn't have the license for GM v6's.

Snob! He used hptuners, I have hptuners with the car already unlocked...

**mskram1** · 06-06-2011

the trans is in awesome working order no slips or noises clunks into gear when getting it out of park on a hill but i guess thats to b expected... you think i could get away with maf tuning it with the aeroforce wideband afc kit???

**mskram1** · 06-06-2011

right now im more concerned in replacing all the worn safety stuff like, mounts and suspension... and ensuring no kr, the last parts list i posted is already at 1500 w/o wheel bearings...

**EJOUIE** · 06-06-2011

not sure of where u are at in TN, but here is a shop by 75 in Kennesaw.
Injected Engineering: Location
If I were to get a tune, this would be my first place to try.

and about the rest of ur budget, fixing broken stuff sounds like a good idea.

**mskram1** · 06-07-2011

i was gonna get hptuners but i have a kid so not much time to sit around and tinker with a tune to get it perfect. is it safe to use the aeroforce wideband afc to fine tune???
