Default STS-V on a DynoJet
I ran the V on the dynojet this morning. Stock I pulled 387whp and 378wft-lbs of tq. The only dyno sheets I have seen have the STS-V at 360-370hp stock. I lost a little bit of power on the tuned ECU. Also the tuned ECU was a little lean at the bottom end. I will probably retune the ECU since I didn't leave it in.

Nice. How much boost does it make? Also, you are really lean for a boosted car. Do you have problems with detonation? How much timing are you running?

Nice numbers Bob! Very strange about the modified ECU though. I wonder what the problem is? Also, is that company still going to build an intake for you?

12psi max. The blue line is the stock tune. I didn't have a tuning software monitoring the engine on the dyno so I don't know where the timing was. I haven't detected any detonation at all with the car.

Very nice, I wish the gto was up there but I'm not too far behind.

Boost, because sometimes atmospheric pressure just isn't enough.

The tune was for another 2006 STS-V from Ohio. I know that they have 93 octane gas and there may be a difference in the tune for 91 octane. I was being careful to see where A/F ratio is before I ran on the street with the tuned ECU. I am a little concerned that it appears to run a little lean with the tune. The stock ECU is still in the car and I will probably have it tuned soon.
The tune is supposed to do the following:
Make the throttle snap open quicker - the throttle opens a little slower in 1st and 2nd.
Cause the internal flaps and bypass move quicker to allow boost to come on faster
Remove the timing retard during shifting.
Make the transmission shift quicker in sport mode
Remove the speed limiter.
Increase the speed in which the timing is advanced.

What are you using for tuning?
