So my buddy bought this car in Tampa fl. https://www.cobaltss.net/forums/comp...-miles-320950/

As it sits 77k miles
-injen short ram intake
- stock turbo
-3bar map sensors
-big intercooler from zzp
-exedy stage 4 clutch
-hp tuners tuned by tucker performance out of palmetto fl. dynojet dyno
-25 psi 93 octane fuel
-3inch catless downpipe from zzp
-stock exhaust pipe with resonator an muffler delete.

 

320hp 340tq

 

315/410 because they didn't care to boost ramp the tune.

 

Probably why the car has a exedy in it now

 

Nah has a exedy in it now cuz hes a young kid that beat on it to much after he got a southbend clutch installed. He will learn

 

310/370

 

Anyone else, Everyone's guesses are a tad low right now.

 

326/397

 

348/412

 

Wow nice numbers on 93!

 

Huh? no #s were posted yet, just curious to see what ppl think.

 

376/473

 

I don't know why I thought those were your numbers. Strange.

Let's try this again. Wow nice numbers.

 

Dyno queen #s (plus it looks to be a happy dyno to say the least.)

Crazy boost spike that'll get you those high spiked HP/TQ numbers... And a need for another clutch lol. look after 5k+ RPM. Power dips like crazy (under 300whp up top)

I mean nice numbers, as long as you're happy with the tune. There is definitely room for improvement though.

 

Holy boost spike, I would be so disappointed with a tune that looked like that. That graph looks like crap. That thing falls off so hard it would be useless in a race. Who tuned it?

 

Hp peaks at 4200? That's crazy

 

For those 300 rpm or less....I'm free

 

Lol! A company in Palmetto fl. I wasent there for the tune an dyno run, but this was the outcome

 

What the **** kinda dyno was that? 473tq on 93 wow. I made 350/380 on 91 and that seems high but those numbers seem unrealistic for a stock turbo non E car. Congrats though

 

I bet I could make at least 130 whp by running barefoot on that dyno judging by this sheet

 

I would get retuned by someone who knew ecotecs.

 

This tuner suposable tuned quit a few ss cobalts...I sent him a message asking why such the drop in hp an tq. an he didnt really give me an exact answer...just said that the stock turbo is to inefficant to hold 25psi all the way to redline

 

I'm over 300 hp from 4,100 to 6,800, it should look something like that with a good tuner.

 

Also talking with other ppl that got there car tuned there. We figured maybe the dyno needs recalibrated...

 

Sounds like there are a few more Torque Management tables that someone needs to discover to allow more airflow after 5,500 rpm.
