Hey all, kinda new here , I have a 97 12v with a 62/65/12 ind. inj. phatshaft , just ran the injector # and there marine 370's , I have .052 holders and 181 dv's, 4k governor springs , ats 3pcs manifold 4" down pipe to 4" out in front of the tire. stock fueling with tork tec ofv valve and banjo's. Other than that I don't really know what's been done to the truck as I bought it through an auction. I'm sure the injectors aren't helping , we just pulled the front cover and it looks like its still running stock timing. seems no matter what I do as far as AFC tuning its laggy and smoky till it gets rolling, top end she screams but I'm more in to wheeling / mudding and the slow spool up and how it hogs up has me looking for a way to make it work. Any suggestions would be appreciated ,, thanks ,,oh I'm running 37" tires with 4.56"s arb's front and rear
 
I'm pulling the pump this week, bad leak with the tappet cover so I'll be in to the afc. thanks
