Need help with spartan tuner...

I am having a problem with abnormally high boost levels under moderate acceleration when running any of the spartan tunes under 210hp. I used to run the 175 tune in the summer with no issues, but now that the temp has dropped, my boost will reach 30+ psi at 2000 rpm. It has nothing to do with the ebp sensor as that was just replaced, and the vgt actuator operates properly. This issue goes away as soon as I load any tune above 175 HP. Not sure what is causing this issue. Hopefully someone else can tell me if this is a problem with the truck or the tuner. Thanks, chad

You try reading the trouble codes with the diagnostics? If you have codes clear them and you should be good.
