Hey guys...over 4 or 4.5k my boost falls flat on its face...I still have compressor spin..but I just go super rich and a big black cloud of unburnt fuel comes out the back. I have NGK Plugs ( 1 step colder) and a Walbro 190lhr fuel pump. Im running the E-manage on a y7 with the Greddy Tdo4h-15g kit. Anybody have any ideas??

 

Bump one time before bed! Could I tighten the gap on my plugs??? Would that help??

 

your problem is that Your SUPER rich and your motor is bogging out. Is there some way you can turn the fuel down?

 

Yeah I was having the same probs last weekend. I was too rich in the higher RPM's.

 

Yeah..im running the E-Manage..but am waiting on my wideband 02 to get here before I start messing around and running my motor super lean (dont want to blow it *knocks on wood*)
