sometimes when i rev high i get a slight backfire. u think im runnin slightly rich? what is the best way to tune that? VAFC? where the best place to buy one? and does it measure a/f ratio or do i need to buy guages? or should i just get an adj cam gear or fpr? im thinkin of gettin my cam reground and gettin an adj cam gear. what would be the proper order of mods?

 

The VAFC will tune it. Got mine used of the black market.

It doesnt measure a/f ratio, it just allows you to change it. The gauges dont respond fast enough to use them to tune it.

IMO, you'l get more out of the VAFC than the cam gear and fpr combined.

If you get the cam reground you'll need the vafc to optimize the a/f ratio since the stock ecu wont match the new cam.

 

thanx

ill get

-vafc first

then think about cam shaft / gear options. i got a little time left before the timing belt should be replaced n e ways. time to sell the venom to some1.
