I think you are talking about me. I did dyno, twice. It would not hold more than 15-17psi. My 461rwhp would fluctuate between 15-17psi. That was even after I sent them back to chip to get adjusted. I hope it was just my set. Also just want to let everyone know chip was pretty good at helping me through all the crap. I will try some TD05's shortly and see what I can do
