no you misunderstand,,,,he can build all the boost he wants....just cant get traction...at about 2 psi he is trying to roll into the throttle and not spin. at 4 psi, if he lets go of the brakes it would just sit and spin.

here is the log...look at the throttle position

 

Cable is correct. 2 psi is all I can do off the line on street tires. I can build all the boost I want. With the 5.3 I brake stalled it and got up to 6 psi. It was still climbing when I let off. The rpms where up to about 3600.

 

Ya i hear you on not having traction. Even with et streets I could only manage a 1.9 60'. With my 20's I can not break boost it at all. There is no hooking on the street with this silly thing
