Thread: Do I need a tune?

A mild tune might be in order. Would probably serve you better to do a CAI, full Headers (Speed Daddy from Ebay, work well at $200), and then HV3 with a tune. Then consider maybe a cam, rockers, depending on your preference possibly some tranny work, shift kits and what not...
Without going the boosted way theres not alot to do with these to make power. Turbos make more power but take alot more work than a top swap goes, unless you have a machinist/mechanic cousin with a shop, and another DD for a couple weeks... then turbo away

So now my plans are just simply, ubend delete, cai, hv3, in that order.

Do I need to tune for these mods? It may be a stupid question, Im not sure... Im just aware of the pcm issue on 08's and the idea is making me nervous about not being able to mod at all.

Also, are there any other recommended mods for the NA car not looking for a top swap? (Dont want turbo either).

Honestly...how far do you want to the go with the car? If your mechanically inclined and have deep pockets you can go well into the 13's N/A...its just a sh1t ton of work. Hell, if you got the transmission for it...you can toss the bottle on it and run 12's.

I'd set her up like this...

Fenderwell Intake of some sort...make one
180* T-Stat
Autolite 606 Spark Plugs
New Wires (Upgraded or stock...doesn't really matter, but PRJ wires are *****in)
Speed Daddy Catless Headers (Your '04+ anyways...so your car doesn't have a U-Bend from the factory...and use the stock catback...you'll thank us)
ZZP HV3 Upper Insert
HP Tuners...you'll need the pro version to tune your car just fine...or take it to somewhere close to you to have it professionally done or someone that knows their way around the 3800 platform...plus, it isn't too hard to tune a N/A car
Yank off your throttle body...and clean it. Then get some 1500/2000 grit sandpaper and a flapper wheel...and polish the inlet and outlet. Worked well on my DBW TB 2.2 Cobalt...since there aren't TB upgrades for the '04+ 3800.
TransGo Shift Kit...get one from Triple Edge Performance
Poly Mounts...get 'em from ZZP...the upper ones. Then, get new solid rubber lower engine/trans mount
As far as it sits now...that's a 14's car if you can drive.

Then...it's either cam or rockers...both...get upgraded valve springs...Crow Cams 105's w/ Retainers...and either get 1.95:1 Roller Rockers from Intense or ZZP...or get a GT1/GT2 Cam from ZZP. With head work on top of that...I don't see how 13's would be out of the question if you were driving it right and it was tuned to its full potential...

OP says he doesn't want boost. Therefore...kinda like beatin' a dead horse

LOL

It's like reading upside down...you can get used to it after awhile.

200 crank

160-170ish at the wheels prolly

i rough guess, because im no expert.

crank - 230-240

wheels - 190-200

maybe

gonna take more then that to go over 200whp Na Id guess 185whp

Meh...my buddy made 200 even with a GT2 Cam, PEM's, L67 TB/injectors, HV3, 3" DP and a custom tune all through a motor and transmission that had over 180K...so I'm sure a non tired trans/motor might have made more power.

But one a bone stock N/A car...expect around 160 or so...since the blower cars make about 190-200 to the tire stock.
