Bac and anyone else feel free to debate it, KEEP IT CIVIL and informative but above all classy... thanx I have no problem spending money on the tune, I'm just interested why the overwheming opinion here is that a tune is absolutely needed, and is it based in reality. Thanks! Can someone please offer a convincing technical explaination of why you would need a tune when installing an aftermarket downpipe. From what i have seen personally, the only difference is that reduced backpressure may result in difficulty with boost control, which can be fixed without a tune. I read for a while and ol / cl delay was mentioned. Please advise. Sandwich ideas thread: http://legacygt.com/forums/showthread.php/sandwich-idea-thread-98448.html Thanks to everyone who contributed!
