Popping when accelerating hard

[craighardy]

I am running hijacker 2.0 and when accelerating hard it makes a pop pop pop sound. Not sure if I'm hitting rev limiter or its misfiring or what?

More than likely you are hitting the rev limiter. Easy to tell on the 2.0, you can turn down the boost and see if it goes away.

I would say rev limiter.What RPM were you running? need to stay around 7900 unless you have the booster flash. What weights and PSI were you running?

 

[craighardy]

Running 19 psi at 2300 elevation with 90 grams(I think). Snow wasnt very good so I couldn't hold it wide open long enough to look down.

Oh yeah, you are bouncing off the rev limiter at that LBS and elevation.

You need a different finish rate on the primary spring in addition to more weight. You can PM me your setup and I can give you some direction on what you need.

Thanks, I will pm you tomorrow with what I all have setup.
