383ss Posted December 18, 2004 Report Share Posted December 18, 2004 Finally got my truck tuned in and some dyno graphs!! it was NOT the ASP under drive pulley that was causing the horrible knock retard mods are C1 cam, 222/222 .563 112 K&N FIPK, ASP pulley, mildly ported TB, tuning I don't have a good baseline run since it would cut off at teh speed limiter on the dyno with no tuning, but it would have been around 290 stock. what do you guys think?? 40 hp for these mods?? I thought it would have been a little higher, tuning supposedly gives you 20hp and asp, FIPK and TB should have been 10-15 all together. that leaves little for the cam Link to comment Share on other sites More sharing options...
