Cost of Flash Tune

[stef69]

Hi Chris, DABOSS has recommended you and just would like to know the cost of a flash tune as I have put a turbo exhaust on my ba xt but have lost back pressure. The system is the turbo cat followed by 2 resinators on each pipe then the standard rear turbo muffler. How or what do i need to do to recover my back pressure although once the car kicks in the power is there. I also have added a bmc filter and the typhoon extra air induction. Thanks stef69 looking forward to ure reply
