Hi jon I emailed you but not sure if it was the right email. are you still around?? I'm trying to confirm a tranny rebuild on your old orient red metallic 996tt and any other info you have. thanks It's a beautiful car but I need more history with all the over revs)) my number is 3602591984 and uwrasta@gmail.com I see you are in oregon now (i think) I'm in olympia wa

I couldn't agree more that Kevin's tune is great. The torque curve is very representative of the feel of the car. But, then again, I'm an engineer so I like the graph. ;-) I'm surprised Kevin didn't make you buy a Durametric and log data. That's what he had me do when I bought his package.

Regards,

Jon

Sorry,but Im not a very technical person what I can offer is that stock, I could rarely see.8 bar, and that was only with sustained full throttle thru 3rd gear. It was hard to see much boost in first gear at all.
The GIAC was hardly different, just pushing the redline up a few hundred rpm,and allowing .9 at the very top of third gear.
Kevin's tune is much improved.
You see much more boost in themlowe part of the rev range in all gears. The extra power actually allows you to cruise one gear higher. Throttle response is better all thru the range, and it easily sees 1.1 and 1.2 bar when you keep the throttle down. Fuel economy's a bit better, as I think I often upshift earlier. Hope this helps AS
