Pulling Timing Error
Hey guys, I was told i had a Pulling Timing problem with my evo, in third gear, shortly after my turbo spools and i hit around 4000 rpm, it seems like the turbo bogs for like a sec, then it picks up again. and then at 4th gear it does the same thing around 3500 rpm. How or what do i do to solve a pulling timing problem? Thanks in advanced guys.

Did you recently install a TBE w/ no MBC? Mine likes to jump around the boost levels a bit just because the ECU is confused with the extra flow...so it sorta does the same thing, but it's a bit more random than your's sounds, just an idea

sorry, I only have a Turbo XS RFL BOV, I don't think it is that because i've had it on for monthsbefore this started to happen. Everything else on the evo is currently stock.

It's your TurboXS. Every single one of those I have seen can't hold steady boost. Get a Hallman MBC. Rock solid.
If you are stoclk I would dump the BOV for a stock or a MR one.

Sounds like the ecu is hearing some knock and pulling back timing
A SURE FIRE WAY to test this theory
Let the tank go almost empty and pour in a couple of gallons of 100 octane of better race fuel - reset the ecu by disconnecting the battery for a coupe of minutes and then see if the problem goes away
If its a knocking issue - I can fix it with a reflash of your stock ecu - you can try a mail in flash for $199 or come down to Pruven for a fully custom tuned flash with 2 hours of dyno time for $299 on sale right now
Thanks
