377...yes higher revving...about that program, best out there at the time is Dyno Sim and its affiliates, get it at www.proracingsim.com it with the pro version is 199.00 or the decent version is 149.00 currently...it works very well and is very accurate. I don't mind high revving, but asking a question...have you ever driven a car that "only" makes power above 4000 rpm...the low down sucks for driveability BUT as you said, the car will be at the track most of the time anyway. Good luck, hope nothing frags on you with 20k invested or more!
