So I just wanted to see what you guys think ill be getting power wise out of my 3.9 with the upgrades I plan to do.
-CAI (done)
- Straight pipe exhaust (done)with slp resonator on the way to get rid of the pops (not done)
- Wams tune
- 8mm wiring kit
- grounding kit
- strut tower bar

I plan on dragging the car so I'm not worried about turning

Also wanted to know how long wams ussally take when you order? First big drag is in two weeks don't know if it will get to me in NY in time :/

should probably get the tune before anything else with your straight pipes. our cars dont like to be straight piped. we loose to much backpressure, in result loosing low end torque. and as for the wams shipping, it all depends on how you order it. if your going to buy a new ECM outright then i would email them before ordering to see if they have any. if they dont it could take up to 6 months to get ur tune.

I didnt really notice much power loss if anything i gained some, just some pops when decelerating and sometimes in between shifts when its cold. But correct me if im wrong but once i get the slp resonator it should solve the pops and any loss in compression. I only deleted the resnoator and muffler, and kept everything from the manifold up stock And stayed stock at 2.5 witht the pipes i used.

If you really want to build it for a drag then I wouldnt go with a canned tune. Id do all the mods you wanted to do then pick up HPTuners and custom tune it to your mods

I was thinking of getting hp tuners, but the cost for getting it just for my car, and on top of it not knowing how to tune wasn't worth it. I asked a dyno shop down the street from me and he gave me a decent price, but the best part is he said I could go back whenever I want with more mods and get it re-dyno tuned for only 100 bucks more.

The only place around anymore wants five hundred just to run dynos for a hour not counting tuning, I think I'm sort of stuck with a premise tune unless I travel or I can convince then to go down.

You can get a wams tune, but likely would have to be updated to smooth out the mods. He can only get it so close without having the car there.

There's also the Trifecta tune, cobalt guys love this. You do the flash yourself through a special cable in your obd port, then you can data log as you drive, send that to them and they'll will go through it, tweak it, and send a new file to flash with. you can buy or rent the cable.
It seems pretty cool. But according the their site they only support ls motors such as what's in the camaro and G8, and ecotech motors such as cobalts, g5s and Such. I don't see very much V6 support. I don't know if this is because they can't/won't do em or just haven't had requests.

lol. I actually decided to jump on it. Because my tune was really inconsistent and I just couldn't drive out to MI to get it tweaked by WAMS. Maybe if I had a V6 and a crabs intake, oh well.

I've so far flashed it once, sent a few data logs and just flashed an updated tune. It's so far running pretty nicely. I can rev it to 7k in park too, wasn't expecting that. haha

So far done -
-K&N Cold Air Intake
-Thunder volt 8.2 mm plugs
-Exhaust (removal or resonator and muffler, put in slp loud mouth resonator)

Up next is the WAMS tune and a short shift kit

Also have ran the car down the strip best time at 14.7 with a horrid response time of .6 seconds will post a pick of the time slip later this was without the wires but I don't expect to much change really counting on the tune and shifter to shave some time off.

over the weekend had a terrible storm which sent down hail the size of quarters diameters and about 3/4 a inch thick. So after getting a estimate because I don't want to go thru my insurance, Im going to fix the Fix the 4 on the roof, and 2 on the passenger side for 450$ and replace the hood all together due to have 12-16 dents, so Im going to go with the AIT concept carbon fiber hood since the price of the hood and painting will be the same, this way I get the benefits of the lightness, and the functional air vents !
