after looking it today, it appears to be boost problems or maybe a weak spark. thinking maybe the n75 or maybe the diverter valve.
its all mechanically sound (within reason lol), its fueling good, etc. It runs fine off boost, but when it starts to come on boost, it starts to run like a bag of sh!t. i dont think there is a leak, as we checked it all over, but didnt pressure test it.
when it hits full boost, it makes a popping sound (fuel cut??) then has a loss of power and runs really sh!t.
it idles fine and apart from the above issues, its ok.
anyone shine some light on this?
