So, based on what we've all been seeing other get from the LNF with just a simple tune, what are your predictions on the GMPP Stage 1 kit?

 

my prediciton, if and when it ever comes out, is that it will absolutely not be warrantied, but will bump it up around 300 hp.

 

i can forsee getting a custom tune would be better than the one from gmpp...be better if they offered wheel upgrades or new turbos (bigger)

 

GM said probably a 290bhp tune. 19psi. Weak Sauce. My tunes run 22-23psi and make 308+hp easy.

 

weaksauce indeed

 

That's why I can't wait till you get down here!!! lol

 

I dont see a stage kit for this car at all. Turbo is maxed out at like 320hp.

 

As for the turbo being maxed out, that's all relative. If you want 23 psi, then yeah that falls off after 5,500 rpms. And power drops around there obviously too. I don't see why companies were offering 7,000 rpm redlines. There's no power up there. Just because you can doesn't mean you should.

 

Should people be short shifting then? My '89 SuperCoupe makes no power above 5200 (give or take 100 rpms; the heads are ****), yet the redline is 5500. My best times came shifting right above 5k. Do you recommend shifting at 5500? 6k? What's the restricting part?

 

True statement. This little tune that everyone is going to have from you will be cool for 5 mins. Kudos for being "the man" when it comes to the TC. Ill be interested to see what people do when they figure out they can use a MAP clamp on these cars. HEHE.

 

My tune will be cool for way longer than 5 minutes. LOL! It's not crack.

As for my tune, it's actually out performing the previous tunes for the LNF by a small margin. I could give you 19psi all the way if you want, so it won't feel like power falls off, but I'd rather put your stomach in the back seat while your tires squeal.

Plus, I am already working with a Hahn Intercooler to research airflow gains, and looking into an upgraded compressor wheel that will allow a slower boost build by a small margin, but a longer power band if it works as suggested.

You all are free to do the wastegate mod too with my tuning too, no harm done there just little to gain.

I suggest nail that no-lift shift as close to 6300 as possible. Go all the way! If you hit it you will fly into the next gear, if you miss it you will have a slight lag then boost hits hard a split second later.

 

On the solstice forum some sources said 290hp/310trq at the crank, so 30hp/50trq increase over stock. However its supposed to come with two additional sensors, most likely a 3bar map and tmap sensor so this would give you additional headroom if you wanted to run more than 22.5psi with the current sensors... assuming hptuners could read the ecm and if it wasnt locked.
Price? Under $1000... gee what a steal

 

i never saw this coming ....ss/tc would be a powerful 4 banger on light mods

 

It will come out right after Duke Nukem Forever

 

Can u say cobalt ss/tc stage 1 = on par with WRX STi stock? i know i can

 

i love women

 

That's right because sensors and tuning are cheap. LOL get real. Try getting those power gains on your car for less than $1,000.

When you are talking tune only pushing 12.8 @109mph yeah I bet you can take an Sti that's stock or lightly modded. Plus they don't have launch control or no lift shift. Sti owners can flame on, but there is probably more potential for the average budget on the LNF than most other cars.

 

I said 300-300, but this is a stage 2 kit, stage 1 would be 20 more. stage 2 40 more

 

Those sensors are maybe $100 each, and as for tuning PCM4less does lnf tunes for $200 that bump the power to 273whp/327trq so yes it is overpriced. It has the gm seal of approval, but honestly who cares.

 

I hope you're right, a bunch of my fraternity brothers are fromwell-to-do families and got STIs for graduating. Me, I had to pay my own way to a new car so I'm getting the 10k cheaper Cobalt. If I could get some light mods and even hang with them around an autocross track, let alone a drag strip, it would **** on their parades so hard.

That, and it would shut them the hell up. Tired of taking crap for buying American. Besting them on the cheap would stick it to them.

 

Roll race em...you'll walk away past 60mph...

 

I'm pretty sure the stock SS/TC is already on par with a stock WRX STi. I'm basing this on Nurburgring track times. I think the ring is a good place to do an overall speed/handling comparison. Don't flame, this is just my opinion.

SS/TC 8:22
WRX STi 8:24

 

Don't consider PCM4less as the standard in tuning prices. They are the Wal-Mart of ECM flashes. Tuning is usually $300-750 a car. Call a local shop and see for yourself. PCM4less could be a business run out of the basement of his mom's house for all you know.

There are even some cobalts dumping quick 60' times close to an AWD launch.

 

Negative. PCMForLess is a LS1tech.com sponsor and shares a huge facility in NC with Tick Performance. They are a heavily respected company over on those boards.

Nothing wrong in changing 3 tables in hptuners in your mom's basement, thats all it takes to get hp out of the lnf, its so easy its almost idiot proof. Sure it'll cost more to have someone personally tune it on the dyno, but it literally takes a minute to do the changes with hptuners, playing with cam and ignition timing will take a bit longer.
