turbo problem, read ###

[HTG]

okay so i turbo'd this SOB not to long ago and still havent found a solution to the fuel cut/hesitation/sluggishness. i have wally 255 and a missing link. im still waiting on my fmu (i know i need it). when my engine is cold, it runs fast and smooth and sounds great. but when the motor heats up it hesitates and just wont go at around 3.5-5 rpms. (can still hear it spooling) 1st gear is usually okay. 2nd gear is when this starts. its always different with each gear. i thought for the longest time this was fuel cut (AND IT MIGHT BE) idk. i just find it weird that it runs fine when its cold. does ANYONE have any ideas/soultions/explanations?? they would be greatly appreciated!

P.S.
- i do not have a boost guage
-and my wastegate description says that: with a MBC i can change psi level from 1-30 without changing springs. so idk what it came "pre-set" on.
-MBC is on its way

could i be running to much boost? is this fuel cut? anyyyoneeee?

You are running it way too lean without the fmu.

i am aware. could this be the cause of my problem i described?

Yeah running it very lean will make it run bad. It will also melt pistons, crack ring lands and pound the hell out of your rod bearings. You shouldn't of driven it one single time without the fmu.

Put a black cloth bag over your head, have someone spin you around ten times, then stop and attempt to hit a bulls eye on a dart board hanging on the wall somewhere in the room with just one dart....if you miss, your engine's doomed. This is the same approach you've taken toward tuning and boost control.

Oh man. Why would you even boost a 420a and drive it without a fuel management set up? Your running your motor very lean, hope for the best. IMO dont drive it till you get a fmu or a sfmu and a wideband.
