It turns out that my timming was a little advanced at the distributor. So I had it set back to stock, my motor is a b16a2 running 7psi.
Now my car bogges down at low rpms and it runns really rich at low boost 1-4psi. It pull hard in the upper rpms and closer to 7psi.

Any way my gustion is should i retune my fuel map? or should i set the dizzy back where it was, even though it was alittle advanced.

 

do you have detonation

 

not enough info..
what kinda engine management? etc..

 

I am using cromepro on a p28 ecu and 450cc injectors. I have not heard any detonation and my spark plugs look ok.

 

are you sure you set it back to a 16 degree advance base at low idle while fully warm?

if so, i would say just re-tune it.

 

i dont think it really matters much where the distributor is set if you tuned the ign maps to the right setting.
