ZelchXR6T Member 25 Member For: 17y 6m 26d Gender: Male Posted 15/01/12 04:34 AM Share Posted 15/01/12 04:34 AM Hi Guys,My BF2 F6 is currently running standard intercooler and piping. The car has been flashed with the stock cooler/exhaust so I was wondering if I replace the standard intercooler with a bolt on larger core intercooler (stock piping) would I need a retune or will the computer learn it? From my limited knowledge I'd think not because its a variable that is regulalrly controlled by the outdoor temperature anyway. Just wanted to double check.Also, what if I added a dump pipe and high flow cat to the equation?I've been running considerably high power for some time now (at 323rwkw) with just larger injectors and want to cool things down and increase flow etc so that I don't lose out on hot days but don't have the bank balance to go all out thanks to upcoming replacement of some dead rear end bushes... :(Your help would be appreciated! Cheers! Link to comment Share on other sites More sharing options...

Who tuned it?A dump and cat will definitely require a retune. Adding a Cooler. It no piping shouldnt, but I'm still baffled about this 320+kw.
