Help! No boost!
Just installed GIAC chip, Hyperboost DV, AWE boost gauge ... am getting only 5# boost wot. I thought my 180 before chipping was a little anemic, but could my turbo be going? Advice, please? Vacuum is 20" at idle, so I don't think I have a vac leak.
Have VW maf, Borla exhaust installed.
'00 180 FWD
'83 Mooney 201 (165 knots)

Re: Unplug ECU... wait 15 mins. plug it in and perform throttle adapt.
I just installed ECU after chipping. It was out 2 days. It should have been cleared. I did let it throttle adapt (about 30 sec.)

Re: Did you touch the N75 at anytime?
No, nothing to the N75. I thought it might be N75. Do you know what the failure mode of the N75 is? It does sound like the wastegate opening prematurely. It's strange that it's constistent at 5#.

Re: Sounds like you have leak... re-check all your tubes
I've checked everything...no apparent leaks. Could it be the wastegate controller? It has a diaphragm in it, correct? Appreciate the input.
BTW, great sig!
