I put a TDo4 on my ZC and it is bogging from a hard take off.And low rpm in each gear. Does anybody have a idea of what is causing this.

 

what's your fuel management setup like?

 

I am running a Rising-rate regulator.My air/fuel gauge is staying in rich.I have tried to mess with the regulator but doesn't help.

 

What is your fuel pressure at idle?

I'm gonna say its because of a larger turbo. Has this problem always happend or just started now? What size exhaust are you unning. a smaller exhaust might help keep some pressure, but thats just what I think.

 

take the RRR off and see if it does the same ----. if it doesnt thats the problem..


if it just started when u put the turbo on.. keep taking the stuff u put on off to see what made it do it. then fix it.

i just hope u dont have a 2" downpipe

 

My car did the same ---- until I re-adjusted the idle.
I was idling really low, like an automatic. I moved the idle back up to normal and it has pick up like a pimp.

 

also what did u do for timing?

 

I have retarded my timing 2 degrees.But I have mess with my timing,I have put it at normal and it still does the same ----. My timing belt is dead on.

 

why, would a 2 inch down pipe do that?
