ok, so i have a 1997 12v,
63/68/14 over e.d. 475 1.10 housing
5x.016 injectors
26* timing
full cut dvs
benched 180 pump
air dog 165
tork tek 60 ofv
built auto
goerend triple disk 1800-2000 stall
o ringed head. 60lb springs
4k gov springs
rack plug
from what everyone is telling me i should be in the 700hp area with this setup, just from driving it i am not impressed at all. i have been tuning for 5 months and am getting nowhere. truck makes 80psi overall and 40 out of the primary at wot, primary starts to build boost at about 15lbs which i guess is when the wastegate is opening?? maintains 45lbs of fuel pressure at wot. right now i have a stock 180pump gov spring in the afc to control smoke. the problem im having is the truck has no low end and slow spool up. i had a single 62 before this and you could floor it from a dead stop and it would spin both tires now it wont even do that when it lights. i have a cable ran to the pre boost in cab so i can adjust without popping to hood 50 times while driving. when i set my afc up i used reguated air to make max rack travel at about 70psi. and set the pre boost just to touch the diaphram. and did 1/8th turns from there. am i doing something wrong? any help wpuld be great im going nuts here trying to figure it out. my next step is compression check just to start rueling things out.
