OK - we are making progress thanks to all the advice you guys are kind enough to give
Adjusted the high idle screw till the throttle lever is just short of touching the fuel line and swapped holes for the linkage and return springs. I also chopped 5 ft off the exhaust, it now dumps in front of the tire. Pipe was pinched by a 1/3 over the axle
Drives more like a gasser now and the peddle feels much better, might even be able to pass a Yugo now
Surprised to see it doesn't blow any more smoke then it did but sure has a noticeable improvement in driveability and it now builds close to 11psi of boost running empty and the EGT's dropped 50*. Beats the crap out of the 2-3 psi I was getting when I bought it. About time that turbo did more then just add to curb weight!
I feel much better about all the money I've fed this thing in the last month - tires, alt, batt, fuel pump, KDP, Belt and hoses etc not to mention the HX housing and injectors. Just yesterday the U joints started to laugh at me - this beast has been eating my vacation money damn it !
