Thread: Tuning question

ok guys heres my question im getting my car tuned by a friend (worked for SLP) and hes going to tune my GTP

Whats the safest and most efficient shift point to set the car to (RPM)

and with a custom tune and my car (Headers, 2 range colder plugs, CAI, 180* t-stat) what should be the right pulley to put on. i have a 3.4 but with a custom tune should i o can i go lower?

Also im new to this what else do custom PCM's do that i should have him do to mine.

Thank you,
Frank

okay ill prolly jus have it at 6 grand and im debating to get a 3.25 or stay with the 3.4 for now my goal is mid 13's and wanna trap 100+
