Everyone,
So, I put my 2015 GT back to stock tune, removed my JLT and re-attached my OEM intake. Did a double check to make sure everything was all set up correct, checked all attachments and hand tightened everything. Took the car for a test run and the power has returned.:shrug: So now...
I have a question and was wondering if any of y'all have the same thing going on. I just installed a Borla Atak 2.5" cat back system, JLT cold air intake and I just tuned my 2015 GT 5.0 with the 93 Octane program. The car has 1500 miles before I installed. I went to SCT and updated the firmware...
Apologies if it's been discussed and I've looked around but didn't see a related thread. What's the real difference between the 2.5" and the 3" besides the sound? Pros and cons, difference in performance? Not sure which one to go with. Sorry for the noob question.
