Terry,

I am very impressed by your coding abilities along with the rest of your team!

I would like if you could give me some guidance in putting the smile back on my face when I bought the car stock. It seemed a 100 times faster, smoother, and crisp without the juicebox.

I believe the wastegate or DV coub=ld be malfunctioning or that there is some parameters is out of wack. I have ran Map 5, 6, and 1.

Currently, the logs are in Map1, I have the most current firmware installed 5.17
along with MHD stg1 flash, and the car has a chargepipe installed. I had to unplug the boost solenoid to get it to idle correctly and to stop throwing codes left and right.

I sure do appreciate your time and effort in giving support to so many people as to myself. Thank you!

Some sort of boost issue here. Not tuning related as WGDC is really high in logs but boost is still lower than it should be.

For starters photo of JB4 control board?

Terry,

Thanks for getting back with me. I snapped some photos of the board for you. Also when I had it out I went ahead and checked all harness connections, flashed the 5.17.T4 iso along with the JB4 BEF pump 071417. WOW what a difference! But still too low on boost levels vs. target. I went ahead and logged a Map5 gear3 datalog for you to take a look at, as well a log from a dig. Anything that can/would help me is greatly appreciated.
