Why would you reflash your ROM after installing mufflers. (without the "muff")soon i will buy this exhaust for my 2.5 + reflash rom.
new rom + full catless exhaust can give close to 200 bhp and more torque.Why would you reflash your ROM after installing mufflers. (without the "muff")
After the second AFR sensor (the 1st really) the ECU has no idea whats behind the AFRs, it does care, it doesn't change anything. And "what" are you reflashing your ROM with?
I'm just curious to see when it's all said and done. I have been part of a tuning group for several years. I have seen many different NA cars come through. Some have full header and complete custom exhausts. My tuner is conservative, but honest about numbers.at this summer i can dyno roll , and post numbers after refalsh rom and high-flow exhaust.:wink2::wink2::wink2:
