tripple C there are other than FASS options out there. I went w/Glacier Diesel Performance (Walbro pump and big line kit, Vulcan draw straw) FASS had some "opportunities" and from what I read here they've corrected them. But, the customer service has been (not first hand just from what I've read here and friends have experienced) not too good. I "thought" I had an issue with my Glacier pump, I called Rich (owner) and explained what was going on and he said "I doubt it's the pump, but since you are going to the dyno next week I'll blast a new one out to you so you have it in place before you dyno, and send the other one back "when" you get a chance" !!!!!!!!!!!! Now that's customer service!!!! It ended up not being the pump but restricted inlet filter and I sent the old pump back to Rich before I figured out the filter issue. Anyhow, do your homework about LPs versus buying what's "Popular". As far as upgrades, GET GAUGES FIRST - if you don't have them already. I went with Westach gauges from Geno's to me they match the stock dash gauges and are cost efficent - had them going on 5 years now no problems - when I upgraded to Glacier LP and bigger turbo I re-sold the 0 - 15# fuel gauge no problem and likewise with the 0 - 30# combo Boost/EGT gauge. I have the following in a tri pod "A" pillar mount - top EGT/Boost, next down is the trans temp (you are an auto so get the temp monitored - went w/Mag HyTech DD pan and pan sensor) - then the last and very inportant one is LP Fuel psi. Once you can monitor "see" what's going on then you can control (lighten the foot . . . . ) what's going on as required. After I did the DTT trans I went w/Magnaflow 4" system (cut off old w/Sawsall in driveway - bolt on Magnaflow), then Mach 1. 6 injectors (90 hp) and an Edge Comp. I did 387 hp/722 tq on the dyno at Fall Brawl 06 with that set up & stock Turbo and air box. Afterwards I let loose with a 64/14 Super Street HTT turbo, Mach 5 (200 hp) injectors and an SB air box/oiled filter and spun off the numbers in my singature at the Spring Fling 07. I'm shooting for another 10 - 15 hp and should easilly break the 1000 TQ barrier when I have my comp upgraded to a drag unit.
It's easy to make these things make HP & obnoxious TQ numbers it's about $$$ and keeping it together - the weak link for us Auto Trans guys is the transmission. My DTT Builder told me I'd be fine without billet shafts etc. up to 400 HP as long as I didn't do 4WD launches and locked shifts. When I ordered the turbo and injectors from him he told me the same thing up to 500 hp and then mentioned I'd probably do closer to 525 hp with my setup. Man was he dang close. This truck is my daily driver and "What" a daily driver it is! I really want to get it down to the 1/4 mile to see what a 7000# truck with an open end rear and 522 hp/998 tq will turn the 1/4 in. I'll be happy if it breaks into the low 15's - I "think" it might do better though - of course no 4WD launches and hope it doesn't spin too much on the 1 - 2 shift . . . with ol` PEG LEG out back :-laf
Have fun, be safe, save your money and buy quality products that will last and do what they advertise, not to mention hold a pretty good re-sale value when the Bomb Bug bites you next. It is as they say here "A Slippery Slope".

As the hippie dude in the head shop used to say with a bigas smile on his face (when we were kids buying rolling papers from him) "Enjoy it Man, but don't get caught by the MAN". :-laf
