We just completed a tune for one of our dealers. The tune included a custom cat back exhaust, filters, and of course PES ECU tuning. The difference is amazing. We gained 38hp peak but 57hp in other places. Also gained 60ft/lbs at 3000RPM. The car sounds like a Gallardo! The dyno speaks for itself. The numbers are "to all 4 wheels" with an automatic trans. Multiply by 1.35 to get the "crank" numbers.



Dynorun video and flybuys can be seen at YouTube - PEStuning's Channel

I will post some Hi-resolution videos of the dynoruns by the end of the day.

 

You guys did a great job on the system. Under load on the highway it just sick!

 

35% drivetrain loss??? Isn't it usually closer to 20% for AWD vehicles?

The sound is incredible though. It just needs a stick shift.

 

I have the ability to do a negative pull on our dyno to determine exactly how much hp is lost through the drivetrain. This car with the automatic transmission and AWD soaks up 35% on our dyno

 

Sounds Great

 

well atleast it sounds amazing

 

Sounds good.
