Wow that a good number. Tuning is everything huh?

rx7legend

yes tuning is everything, a guy here says that i have to change my injectors cause there probably maxxed out and i can't run more than 10 psi on stock 550s. but i did 220whp on stock injectors and the duty injectors cycle was at 22%, the safc duty cycle limit is 50% so im not even half way there. i don't know why this guy says im goona brake my engine lol. to each his own

Can we be a little more detaile please??
Your making 220 on stock injectors fine, but what about the rest of the setup??
Do you have intake, exhaust, what is your boost at????
I really don't think the injectors are at 22%. It must be higher.........what is your fuel pressure set to??

rx7legend

ok, the rest of my setup is:

rb exhaust
safc2
turbosmart bov
turbosmart boost controller
walbro 255 fp
stock intake

when i did that dyno run i was at 11psi. and yes i was wrong when i said the duty cycle was at 22%. what is set at 22% increase is the safc and thats at 7500rpms.

I´ve been running with stock injectors for a year and it does "boost" them a little bit, but i think its even more effective on tuning down 720cc´s insetad of "tuning up" the stock injectors.
