You're on 1 turbo and running 1.5 bar? I find that very hard to believe.
2nd turbo not going in could be for several reasons. Check mkiv.com, there is a section with repair manual pages. There are scans there of the way the sequential setup works. Check the actuators, wires etc.
yes it is boosting 1.5 on 1st turbo and 2nd does not go in because when it was ok was boosting 1.1 then 2nd goes in and boost til 1.6 than last week the car was boosting 2.1bar and i don't know why with out any modifications and remember i have a stock compressors. so i tried to lower down by the evc and i adjust it 1.45 and the car is misfiring on full throttle but if you give throttle smothly it will not misifire that much
My 94TT is BPU+ and I just got a Haltech Elite 2500 to go standalone. Sticking with stock fuel (upgraded injectors though) for now, and would like to drop in a fuel-pressure sensor somewhere. Is there any easy spot to do that ? Maybe the banjo/union bolt on the existing fuel-pressure...
