next to me and says "Hey, what are you doing?". I was in the middle of cursing the recurring throttle cut bug which still plagues me :-/ But I thought the outline of the door and handles looked familiar... I look closer ... he's driving a 93 Pearl UrS4 !

So we got to chatting ... he has a full RS2 conversion. I explain I'm doing data logging on my latest GT3071 software drop.

So we do some highway speedo calibrations, my timing is teh suck but I still pull away nicely ;-)

We swap cars, and I got to drive an RS2 conversion for the first time. It's nice, very smooth like stock, but kicks in later i.e. more lag. In the end I'm so glad I got to ride an RS2, because now I really appreciate what I have: GT3071 is a torque monster !

And surprise : his car had the exact same throttle cut issue in 2nd gear at ~4K rpm, and I notice his Wastegate spring has been hyper tightened. . . hmmm

2nd surprise : he's lived only a few hundred yards down the road from me the entire time...

The GT3071 has lag a bit less than the RS2, flows to 450chp, holds steady up top. The Gt30R has more lag then the rest, flows to 550ish chp, and CAN boost 45psi.

It sounds like you meant that the RS2 has a bit more lag than stock. How does the lag of the RS2 compare to the gt3071?

I installed a reconditioned head/valves. But the only flow changes have been from Phenolic Intake spacer, Polished & Coated RS2 EM.

That's a lot of power to be putting through 'em!

like 550+wtq

Jeez man gimme a break :-/
