Effects of installing my *new* SLP Smooth bellows
By the SOTP dyno, I didn't notice/feel any more power. But then again, when you have 400+rwhp, it's hard to feel 1-5 hp, at least for me anyway. I'll have her dyno'd again when I'm done tweaking the OLSD tune.
FWIW, this bellows replaced a stock '02 Yukon 85mm MAF (w/ screen).
