Car Backfires
 

When I was driving my car today When i Accelerated 3/4 to full, at about 6000 to 6500 a loud bang happens, it sounds like a backfire. I didnt notice it before I installed my GM MAF and MAFT V2.02. Also I took the cover off the MAFT and when its at high RPMs or on off playing with the trottle the red LED blinks. What could be wrong? I do not have the 2 wires hooked up I read about it and one is for tuning with RPMs and the other for like nawz. If someone knows what it could be let me know PLEASE!
Thanks,
Mike

Anybody know what this could be?

I had my blow off valve being vented to the atmosphere and sometimes it would backfire when I let off of the gas. So then I reconnected the hose and it was fine..

Dont ask why

Do you have a logger or anything?
I used to think I had bad fuel cut/stuttering between 5500-6000. Car wouldnt rev above that. Then I got a datalogger and realized I was riding the rev limiter, I just had a REALLY slow tach.

I do not have a logger. I really need to get one tho.
