I have a 2018 Jeep Cherokee SRT. it has JLT intake, 160T, 90mm TB, kooks LT's with no cats, 3" dynomax exhaust with X-pipe. I am wondering if getting a tune would help with these mods? I am being told that my jeep is a runner. It has run 12.58 at 109 like this in track mode. Should I wait till it is cammed to tune?
Thanks,
