Diablosport Forums

I have tried the srt forums and i cant get any help. I put the 93oct tune on and it was working great so i decided to turn up the boost. So i was running at about 12.0 afr so then i tried to give it more fuel and it didnt and im still running from 12 to 12.4 afrs( Not Good). My mods are 3 in downpipe to 3in straight pip to the ground, k&n drop in filter, agp wastegate holding 15psi and the diablo. Any ideas of whats going on?

your probably running out of fuel up top... Put the boost lower, or get more fuel.

i would also buy a walbro 255 fuel pump. Since i have this fuel pump, i can hold more boost with near -1.0 afr. Rewire the fuel pump with 14-16 ga wire, gonna make you -0.5 richer on afr too. Other option will be stg2 injector, but need a custom tune to rescale your injector duty cycle.

Btw, i hope you check your afr with a wideband, not inside the diablo datalog, Because is only a commanded afr, and it not accurate at all. I did the test ...

I have an autometer wideband so i can watch my afrs. Ill have to do the rewire this weekend ... thanks!
