they underrated the cars from the factory for insurance purposes. sure they make 205hp at 5600rpm like gm claims, but the lsj makes power all the way to redline (6500rpm on a stock car). thats why they dyno more than what they were rated at.

 

Lol my last run was 13.9 @ 102mph with intake, muffler, gm stage 2 kit, 2.79 pulley and that's all. Since then I did 60s, traction rods, header, catless dp, meth w/ 5gph nozzle. The guy dynoed me at 247 whp and 218 tq. He said I shud run with these numbers 13.3-13.5

 

dude you need a better tune than. Read around with your setup you should be at about 260+ hp especially if your running meth with the setup. Fire your tuner

 

you had a gm stage 2 kit running a 2.79 pulley ?? yikes !! that's a big no no. thankfully you upgraded to 60's and a custom tune.

i thought the same thing, but he was dynoed on a mustang dyno which usually reads lower. his tune is prob ok, and he is prob in the 270whp range.

 

What I don't understand is one of the ppl on here was tuned by the same person on the same dyno w less mods n he dynoed at 270whp.

 

I dont think any of us will be able to answer that....

 

So what u think I shud do retune or leave it? I bang w slightly modded lt1 camaros and I beat jeep srt8, modded srt 4 evos modded trailblazer ss. So doing that do u think my tune is fuked up or its good?

 

Well we will figure out what these cars come stock to the wheels with in October because we are having a midwest meet and dyno and all I have is a cold air intake

 

^^ We already know

But i guess more data wouldnt hurt haha...

 

x2

 

With the mods that you have in your signature and a proper tune you should also be right around 260-280whp. On 60lbers, 2.8, meth, 23 degrees timing, I put down slightly over 280whp on a dynojet that reads a lil high. So I was probably right around high 270s with room to grow.

I have been tuning cars for awhile now and I have tuned a few ottp stage 1 cars on and off the dyno. Depending on there supporting mods the gain is absolutely incredible man. You can seriously make 40-60whp over stock with the upgrade. Think about it, your dropping pulley sizes, upgrading injectors, most people have exhaust work/cai done already, and then the tuning process.

Before you doubt me and start calling bs about a ottp stage 1 kit putting down those kinda numbers do some research. It's not a good idea to bite the hand that feeds you.

 

Our kit is at a new lower price now. http://www.ottperformance.com/Cobalt...duct_info.html

I advise you guys to check it out, the price can't be beaten and we have 70 plus ecu's in stock now so there is no more waiting.

 

not a bad price for this setup (for example)
considering the injectors run ~$200

 

Damn.. you can get it to work out to 300 bucks with the right options..

Go OTT...

 

Just wait, we are a little behind schedule right now but the first week of october should bring some new things to market, along with even more savings on products. The 3" intake has been reduced also.
