Need advice. I just purchased a FRPP TVS that has been ported and polished and includes a high flow L&M elbow along with a 2.59" pulley. I'm currently running a 2.59" pulley along with a VMP 93 octane tune on my '08 KR. Should I retune for the TVS? Right now I just plan on installing the TVS and leaving it alone; maybe later on changing the TB and injectors. I don't want to have to keep purchasing different tunes every time I make a change. Your help is appreciated. :beer:
