Hey guys I can’t seem to find and answer to my issue I’m having

so my srt has these mods
5858 precision turbo (19 psi)
750 cc injectors
450 walboro fuel pump
6AN return and feed lines
turbo smart EWG
Fuel pressure regular shows 60psi at idle
Air fuel ratio is at 18 at idle


my issue is when I go wide open throttle, the car will back fire and spit and I loose all power
And I have to let off, it won’t do it if I ease on the throttle. Anyone else have this issue

idle AF at 18 is no good...it should be around 14.7... could be a sign the tune is way off or you're having fuel issues.

I have the Diablo sport tuner, how can I adjust my fuel air ratio?
That question means you shouldn't be adjusting your fuel tables.

I have no idea which 750s you have, but the flow at 60 psi should be more than enough fuel.

18 AFR was verified by what device?

Do you have a scan tool that can watch the factory upstream 02 sensor?

get ahold of duster360.
