Just got my car tuned at Jennetty Racing of Waterbury, CT. What a great call that was. The car put down 296whp/308wtq. I was hoping for just over 300whp but I think that was only to say that I had over 300whp. I can't complain. It was wicked hot yesterday, about 90 degrees, so maybe that would have an effect on the numbers? I don't have a clue. I know colder air helps. The ride home was ridiculous. Second gear wheel spin is just stupid. I will post up the graph when I can.

Performance mods to date are an Injen Intake and Charge Pipes. I was going to wait on a turbo back exhaust system from Modern Performance, but I called and they said it wont be for months. Maybe that will free up some power when I bolt that on.

hmm must not be an aggressive tune then, but as long as its a safe tune your good.

You have to realize all dyno's are different. A dyno is a tuning tool not a standard measurement of power.

For all you know it could have been 100 degrees with 90% humidity and he was on a dyno jet 24 instead of the 48.

well when you look at stock ones with tune at 320+whp then with his mods at under 300whp... I dont think a dyno would be 50whp off? That tune is known to be rich and not as high as custom HPT.

xSlowbalt09x

it was very hot, 90+, and pretty humid. and i have seen cars with comparable mods with lower numbers. i was very happy with the result and i am pretty sure Ted has alot of experience, he wouldn't let a car go out of his shop if he didnt think it was right.

i have no idea what i am talking about when it comes to dyno's but they have a 'Superflow SF-840 Chassis Dyno'. that is from thier website.

Janetty uses HPT to tune vehicles. I keep meaning to throw the sheets up... I am getting to it.

w/ out a base line, these dyno #'s really dont prove anything. if you baselined 260, and afterwards ended up w/ 296 but another car base lined at 220 and ended up w/ 256 chances are that is the dyno, and the cars would perform similarly.

you both would have gained 36 HP from tune/parts.

are you seriously saying a SS would base line at 260? or just as an example. On the same dyno etc. SS's shouldnt be much more than 10hp away from eachother... anyway like I said in my first post. It seems conservative, but hey if you are happy with it thats what matters...that and if its a safe tune.

Readouts state that A/F stays constant at 8.0


hope that helps...

Billsac

Wait! what? 8.0 a/f ? WTF??

Tofu made right at 300 with a tune only. 320 WHP - 29X WHP is less then 30 WHP off who taught you how to do math?

ALL DYNOS ARE DIFFERENT, ALL BAROMETRIC PRESSURE IS DIFFERENT, TEMPS ARE DIFFERENT, HUMIDITY IS DIFFERENT.

So last time I checked when the 4 things that determine dyno numbers are different, then guess what????


YOU WILL GET A DIFFERENT READING.

You cant honestly think his car is running at 8.0 A/F.


You do know that maybe the shop owner just disconnected the A/F bung and had it read 8.0 all the way across.

Pretty much what I am saying is that the Wideband wasn't connected to his car if it was it was not working.

xSlowbalt09x

that is exactly what it was... he said he was going to install a wideband, which i assume measures the A/F, but he never did. that would make sense then because the rpm readout sheet stated that the A/F never changed.

Welll..... you have a horrible torque curve...

Drop all the way down to 200ft/lbs at redline...

1500 rpm powerband.... UGH

Spectral

Where are there stock SS/TC putting down 320+whp on JUST A TUNE.

1badBlueberrySC

Not tune alone... I did make 309whp and 339wtq (tofu got 314) tune alone

Spectral

You and a handfull of others have broke 300 tune only.
With some bolt on and a tune 320+ i can see but if someone hit 320whp on just a tune i wanna run at their dyno
