took the 2003 m45 to raceway park nj

[viperatc1]

what's holding this car back is the transmition programming. it shifts way too soon and to much delay.i also own a g35 coupe auto which shares the same exact transmission and ratios but shifts so much firmer and also in manual mode u can shift at redline all day! i could understand them changing the firm shift to soft but the delay is really bad. and it shifts anywhere from 2-300 rpms too soon! just take the car out and watch the tach you will see what i mean. please post some feedback on this.i heard that the 02 q45 had this problem and was fixed with a program from the dealer.
