Thanks I am enjoying it, still getting used to the new exhaust, first time I have had a hfc, I am getting tuned tomorrow at cbrd speedfactory I'm excited!

 

A tune should help eliminate it though right? Should keep him from running rich?

 

Pops happen when you let off the gas quickly and the injectors are still dumping tons of gas. Or when you bounce off the rev limiter.

Basically anytime the fuel doesn't get burned.

Cats usually burn this fuel off for you, but without cats, you pop and fireball.

 

the hfc can still give you a pop, i still have that on mine normally 3rd gear and when it shift to 4th but on tp it is always there like an orchestra or pill collins.

 

Just got tuned and it does seem to help, only heard it once in a 7 hour trip from CBRD back to my house, thanks for all the comments and help, its greatly appreciated.

 

I miss all the backfiring. I don't get it as often after I got tuned.

 

you made 259 with an intake uicp and tbe?, i would of expected a tad more then that.

 

peak numbers were 272/289... 25.0 psi...

the car was a little more knock prone that most, I chalk it up to the fuel and heat (plus stock fmic )

cheers
