i tow pritty heavy with my truck, she is also getting a new head gasget at the moment but with a good set of guages and a little know how, i wouldn't fear towing anything. you'll finde that these trucks hold up quite well to power, at least mine is, Nadierpoint is right over fill the tranny by a quart. get a pyro and boost guage. 1600* and 60psi. and go from there. the 3200 gov spring is the best $20 i eveer spent on my truck, my M&H fuel pin set is the best $400 i ever spent( i got all of them they only cost$100 each)

 

Thanks for all the good info guys. Out of all the M&H fuel pins witch one do you use the most (happiest) with?what about all the free upgrades? Advance pump timming,turn fuel pin 90*plus possible grinding,turning star wheel,smoke screw. If I under stand you save the main fuel screw for last? Would free upgrades help? THANKS ALL OF YOU!!! This realy does help.

 

If your towing heavy I would leave teh timing stock or maybe 1/16"-1/8" bump TOPS. Dont just turn teh pin 90* pull it out and make sure the deepest part is facing the front of teh truck. IF you get an M&H pin it will replace the stock one though. Leave your star wheel and smoke screw were they are, all they do is give you off idle smoke. No real performance gain. Yes leave the main screw for last. I would not go to much on it if your gonna tow alot.

 

I just put the M3 in my truck yesterday and its awesome. Not to smokey on the bottom and they all fuel hard at the top. Definitely a well spent 100 bucks.

 

What does the timing advance do exactly? I heard it would lower egt's and spool up the turbo sooner. I figured that would be good since my truck doesen't have an intercooler. Have you heard about grinding the stock fuel pin. I've heard some say grind the ramp and some say grind the bottom off???

 

I'd just buy a pin before I messed with that

 

Be willing to sell one of yours?
