I dont know much about 12 valves, but if I were you, I would back the fuel off a little bit, and see what happens. this might result in a little more HP, and thus more wheelspeed. your smoke is a little TOO black, which isnt a bad thing

truck looks great, sorry about the dent!

well i would be curious what a set of 191s would do for you. i put a set of cuts in my dually for the pull and my god. it smokes so much it was embarassing. never cleared up on the highway even at 50 pounds of boost. i think you may not need the big dv's, now that you have a good set of injectors. but this is just a guess on my part. on my dually with 370s they just seemed to add smoke. i could not notice and real hp differance. and i am starting to like the 180 hp pumps a whole lot.

sorry to hijack garrett's thread but do you know that M6's dont give you any more power than a mach 4 with the HRVP44?? you might be able to pull them and sell them to someone with a SO pump and get some mach 4's and pocket a few bucks

I turned the fuel back a little bit as a trial.. I only slid the AFC back towards the firewall all the way.
Gained nearly 300RPM pulling in 2nd gear on the track.. Went from 3700 to nearly 4000RPM in 2nd gear.
I think it pulls a lot better! Next thing is to slide the plate back a tad.

Yeah, I've read that, of course the day after I ordered the HRVP.....Oh well, my truck has always like higher fuel settings on the boxes than most folks suggest for max power. I'll just have to tune it and see what I end up with.

dont ya hate that...finding out a day too late. talking with doug at PDW saturday he said im done fueling wise until i change the VP, but he said with my current combo after the head work i should be over 500hp

of course when i hit the lottery next year ill be getting a HRVP, a helix 2 cam with valve springs, and a redline box
