It turned out nice, gave him one turn on torque control, a little on rack limiter, maxed out full speed, and the inside idle was stuck. So had to remove the screw with stuck nut on it, repaired and put back in, so no idea were it was so started it holding the throttle by hand and turned idle in until I had a nice idle. then of reset the outer idle. His is manual so set it for good shifting. Boost is maxing at 10 psi now, waste gate was holding it back at 9 psi, readjusted now. egt's get to 1250 in a 0-70 mph run. So really did not want to push any higher. He is a bit of a full throttle driver, does drive well though. Did also ream pc's out .010, and he had some rebuilt injectors we put in. Did repair the air cleaner mount (missing tab on intake manifold, as well as crack metal frame for eht ebase of the air cleaner) and put a proper one back on instead of the sewer pipe filter, so fresh air from outside now.

Did you advance the timing at all?

How does it run compared to yours?

No timing advance, would have been nice to do but ran out of time. It could use a little more advance. I would have liked to do a valve adjustment too.

A little slower then mine, but still very nice. Very good drivability. His trans will allow faster shifts, mine will grind second if I speed shift it.

That is something he can do as long as he marks where it is now. With the PCs opened up, he can run even more timing which will increase the bottom end torque and lower over all EGTs.

Also of concern is his cam timing.
