Just ordered my C&L racer intake and xcl2 from brent at brenspeed. can't wait to see the difference i keep hearing about. I didn't let him know that i have 20 inch wheels on the car should i call him and tell him that? I figure i should so my speedo will be correct with the new tune. What type of gains should i get with this with a 93 tune. he is also giving me a 93 octane tune xpipe so when i purchase the xpipe i will be ready to go. Will i have noticeable gains doing these separately or should i just do it all now. I would like to wait on spending the $200 till later for the xpipe but if i am not going to notice a difference doing them separately then maybe i should just do them all at the same time.
