has it always "overboosted" or is this new ?
did you try new boost control lines or check for tiny leaks,just pressurize your source, i use a compressor with a regulator set to my crack pressure (off boost not manifold pressure) to check the WG function and for leaks.
other than that it could just be your boost control tables (i dont know jack bout that)

what new changes did nemo do, and i presume you save all the maps so you have an original (good tune) map to compare your last map to

theres too much duty cycle in the boost control probably..we set the boost when it had a boost leak

i will email you a cal. i wish you were up here or i was down there. remember we had an issue when tuning on the dyno, so it really was always malfunctioning . i connected the wasegate to the turbo and it hit about 13 pounds, then i connected it to the stock solenoid the same way that it is in the picture on the car( with only the bottom of the wastgate connected and it hit 17lbs. i kept getting some kind of cut when hitting on it but i guess that was ignition cut from the 2step.

jay check your email, i hope it was sent correct. nemo changed some numbers in the boost map, but that didn't work. jay it may seem as if i messed around with some things here and there. so feel free to correct something if it seems out of place.

jay have you gotten my email at all.

never2muchboost · 06-04-2009, 08:17 AM

yes got it, what am i supposed to be looking at in those logs? you never went over 14 psi in them. i looked at the tune and compared it to your tune i gave you and a lot has changed.check your email

sorry jay,i sent you logs of the turbo to wastegate connections, showing that the wastegate works . i am sending you a log of the setup with the contoller and you will see that i reach 34 and then i guess i get fuel cut. i had to disengage the wobox due to getting ignition cut earlier.
