Ok so i orderd a tuner from brenspeed and i have a frpp cai and soon to have flowmaster axlebacks, my concern is do i need to buy a custom tune where i tell them my mods or no? i bought the one with 3 custom tunes and i will be running the 91 octane tune. thank you for your time

 

I put the FRPP CAI on my V-6 about a month ago. I talked to Bama on the phone, about my GT take off duals, and they told me w/stock mufflers it wouldn't make any difference on the tune. Call them. I told them my set up, and had the tune via e-mail about 10 minutes later....

 

if all you have r take off duals &cia then no, there is no need to make a phone call. What you have won't effect it. Now lets say after your tune get a o/r mid pipe or gears (then it may be a good suggest to ask. You won't need to "upgrade tune" until you really start going at it... modding.
