The 1-2v shift is rarley smooth as it should be regardless of throttle level. The serious shudder issues are always under light-moderate throttle and never at WOT. Honestly I am afraid it will cause an issue so I have not been at WOT for the last few days. It did it again where it shuddered REAL hard from 1-2 at light-moderate throttle coming through a rolling stop at a stop sign. My 10 year old looked over and asked "dad, what the heck was that?"
Flashed back to stock and loaded up my VMP tune. Hopefully I can get answer from Bill. Til then the PHP tune will have to sit on the shelf. I dont have 15k on my truck yet and do not want to shorten the tranny lifespan.
