Finally, nice enough weather for the install. It took about ten minutes and I have NO mechanical skills at all. No lights or codes and I did not unhook the battery.
In my opinion there is a huge difference in the throttle response. It took me quite a few practice runs to tame the jumping but after that there appears to be a big improvement. The lag is gone and a big jump in response in the first three gears. Money well spent and the fact I could install it myself (thanks to the excellent instuctions provided on this forum) really made this worth the money. Thanks TVT. Would recommend to anyone.
