Just put my Dp tuner in and love it, however just 2 concerns, one in the 40T settin it sort of bangs when the torque converter locks up.

Second: this has bin going on before i got the chip but my turbo when the truck shifts is making a screeching noise. It sounds like the turbo is slowing down and screeching inbetwwen sifts but MOSTY when The TOrque COnverter locks and it shifts into OverDRive..

what do you guys thinks about these 2 things? THANKS

If by 40T you mean the 40 Tow program then yes, it will shift hard unloaded. The Tow programs were designed to be used when towing and the shift strategy is programed accordingly.

Have you checked your turbo for bearing wear? Check the radial runout and shaft endplay. If the condition is severe you may see evidence of the compressor wheel striking the compressor housing.

Also check for boost leaks,mine did that right before i blew the boot off.
If you dont have plans Sat. we are having a meet at the Somerville circle TGIF come on over and we can take a look at it,check out the post in events and rallies

whats the best way to check for turbo leaks besides just checking all boots are tight and on all the way?
