TPS and overboost problems

I have a 1990 miata with a 96 motor. The turbo is a gt2560r. I did the tpsmod on my magasqurit and I getting a bad signal in tunerstudio. I've truest tuning the car with just kpa, now I have a overboost problem. The turbo has a integrated 8lb wastegate and I'm seeing 15 lbs at full throttle

The data log does not show more than around 5 psi of boost. I need a data log that shows the overboost problem.

The TPS looks like it may not be installed correctly; I'd test its output with a voltmeter.
