My car has a diablosport chip on it and was dyno tuned last year. Since then I have switched from factory 2 1/4" catback with flowmasters welded in to a 2 1/2 magnaflow catback. Also have a JLT CAI sitting in the garage that I still need to put on. At the time of the tune the car had the bbk cai on it. I wouldn't think that the changes would be big enough to cause me to need a fresh tune. What do you guys think? Car is a 97 cobra with the usual bolt ons.
