Hi I have just converted my rb25de to a +t and have a little problem.
When i took it for a drive to see if it all went as soon as I hit 5psi the car shudders big time and wont go over it. it is also on boost all the time when i was cruising under the 5 psi mark. I think it is an over fuelling problem becuase it pumps the black smoke out and I did a little skid which went to 7-8psi and it shot flames out the back.
I have a fmic
3in exhaust
extractors
gtr injectors with a 6.8ohm resister pack
CHIPPED ECU
wasted spark
new spark plugs
any ideas. I have cleaned the afm which was a problem with the engine chasing at idel before
