I have the smallest spring in the waste gate so its between 7-10 psi, they might have set it higher a bit to see if it will make power to 15. True it is, I'll know more about the engines compression hopefully today, but I'm really thinking the trans is just f'd, when they were getting the shifter to move more freer they noticed on the throw on the valve body for gears that its wider then usual, so if you want a good 3rd, park is questionable that it goes in, or the other way, good park and questionable 3rd. I think that tranzact just built a crappy trans this time for Louis and I got it before even he ran it. So its all new from them.
