TRUE OF FALSE Power Loss After Intake and Exhaust Setup

ghotnit

When I did all the breathing mods on my car (intake, test pipes and exhaust) the ECU was not happy. It was not able to cope with the changes and fluctuated from lean to rich which caused a power loss and a crappy running car. IMHO, when you modify the breathing, especially the intake, you should (read "need to") tune the car. That is the only way to get the benefits from the money you spent. If you are not planning to tune the car to match the mods, save your money. For the exhaust, if you want to change the sound, get an axle-back system.
