    Made more pulls than I could count or keep track of.... I needs to get a bigger top pulley and see about knocking the boost down to around 3 pounds 4 pounds hit 603 hp under 5700 rpm and 6 pounds made 625 at 5500. I forgot what we ran it up to but at 6 lbs on one run we were over 640.


    My 6 lb pulley made 650 TQ and the 4 lb mad just over 600...

    The printer at the dyno shop died..So I have to wait a few days for the detailed print outs.

    I think you should turn the boost up, not down!!!
    Getting bad advice is unfortunate, taking bad advice is a Serious matter!!
