Do you have a Wideband or EGT?

James

 

are you tunine on a dyno, or is someone tuning for you?
if you aren't tuning on the dyno I would either buy a WB02 and EGT,
or just go to the dyno and pay to use theirs.

 

the safc2, someone is going to tune it for me on a dyno tune.

the safc2.

Time for group dyno day!!

From what Ghetto Dave told me how much fuel you have will somewhat determine how much power you'll be able to make safely. He told me he doesnt prefer to swap in larger primaries.

 

he doesnt prefer it but do i still need more fuel because i have the hybrid? on rx7.com hp calc, i put in x2 550cc and x2 720cc. then i tried it again with x4 720cc i get about 40hp gain

You might run out of fuel with just the 720's up top. Try and grab some 720's for the primary's. Running equal sized injectors makes for a much easier tune with the safc as well.
