Dyno Tune Question

[shaolinmonk777]

Hi, Im sick of my BBK o/r H-pipe making that popping noise at WOT all the time. I have a X-cal 2 and was just wondering if I got it on a dyno and adjusted the a/f would that clear up that noise. Any help would be appreciated. Thanks.

nobody?

You might try leaning it out a little, but popping with an o/r H is normal so i wouldn't worry about it too much.

I doubt it, what kind of mufflers do you have?

Thats whats causing it. Flowmasters do that, mine did, but now i have bassani. If you still want the deep sound, but hate the popping, you could get a mac catback.

I have Magnaflow and it sounds like a shotgun blast between shifts. I have an o/r H-Pipe.

i thought you could adjust the a/f ratio and it will go away. if not what should my a/f ratio be at.

You maybe able to, but it won't completely go away with flowmasters. My 96 popped with flowmasters with stock H and bassani Catted X, plus my 69 would do it too.
I've heard mac's don't have that problem though.

could also be an exhaust leak.

You know, I hardly ever get any popping on my Mac o/r h and Mac flowpath catback...interesting.
