All the way to 5,000 without the 2 step?... its because your against the Converter... and the more power u built the more it wants to drive threw it... you can give bolth a try... I allways set the 2 step about 2-300 rpms under stall speed or sure the rpms of the two step to dial in the boost that you want to leave on... 10psi and 5,000 rpms sounds like Great numbers to leave the Line with... esp with the chassis setup that your running !

 

Thanks man, I was thinking there was something wrong with the converter, tomorrow I'll be testing the truck I hope it works with the help of everyone here.
