Hey guys, my microtech is tuned pretty well at this point. Just dynoed 370 rwhp at only 11 psi (just installed an EVC, will dyno soon at 14 psi).

However, whenever I left off the throttle after a full throttle/boost run (staying in gear), I get a ton of fuel dumped out the tail pipes, for what seems like a few seconds.

How can I remedy this behavior?

thanks,

I believe that's the Anti Ricer Flame System

 

Absolutely sure it's fuel? (not water condensation?)

How about the condition of your injectors?

 

just adjust the 25 and 30inhg maps till it stops

 

the real problem was that my POS K&N stainless fuel filter was reducing my fuel pressure, so I had to add heaps of injector pulse time for higher rpm range to compensate. After installing a Aeromotive filter ($80!), and taking out heaps of fuel for the higher rpm range, everything seem to be fine now. No more big puffs of smoke.

Still get Big Boom/fire ball out of the tail pipe from time to time though.

A nice lady actually pull up and warned me about it last week
