I have a procharger P-1SC on the way for my 2002 F150 with a 5.4 and I have a couple of questions.
First off, ATI is telling me I don't need a tune, they say just install the kit with the FMU and I'm all set because it's an intercooled system. Is this safe as long as I run the kit stock with the advertised 8-9 PSI of boost?
I do plan to run it on a dyno post-install to check the air-fuel ratio and all that, just wanted some input as doing injectors and a MAF + dyno tune is a little on the expensive side.
It'll be safe but you are leaving a LOT of power on the table without a proper dyno tune. Get the 90mm L-truck MAF and 42# injectors, get it tuned, and really make the most out of the investment. (Then go to a 12# pulley, full exhaust, transmission shift kit, and maybe a little spray...)

the stock ATI kit leaves a lot of power/performance on the table
make sure you install a shift kit to help the trans or else your gonna have trans issues
make sure you add the boost-a-pump before you try to run the larger inkectors though (the ATI pump with the kit will be safe for 42# injectors)
with the FMU there is almost no point in a dyno cause you can't really tune it, you can dial it in a bit better but the dyno tune with the fuel mods and 90mm MAF will improve your low end and mileage
if you haven't ordered it allready get the D1sc upgrade and the 3 core innercooler if not you'll regret it later.

I never installed the FMU in my kit. Bigger injectors, Pump and MAF with a tune was the route I took.
BTY I got my Troyer tunes last Friday the 12th. WOW! What a difference.... Local dude who sold me the kit was OK for tunes but the Troyer tune is tons better.
I have an 01 f 150 5.4L and I recently installed a D1sc and all I could get out of it with the included 3.7" pulley was a mere 4-5psi of boost. I'm now running a Reichard racing's 3" and am seeing 9 psi, after adding an idler to the backing plate to get more belt wrap on the blower pulley with the cheesy 6 rib configuration. now with 9 psi I'm getting a little knock on the upper rpm's so I'm going to upgrade to a Lightning maf and 42# injectors and have it dyno tuned. I'd work out all the belt slipping bugs and pulley size before getting the thing tuned though. Oh and also, I hated the noisy fuel pump that runs in series with the in tank fuel pump, I could hear it over the exhaust. "In tank" walboro 255lph pump costing 115, well worth it, and silent. I just went through a lot of stuff on the install and such, so pm me if you can use some advice or help.

Just a quick question. Where do you reccomend I get the 255 LPH in tank pump? I installed the kit the other day with the ATI booster pump and good god that thing is loud. Thanks for the help.
Get ahold of Pilot on these forums if possible. He can help you avoid a lot of installation mistakes that are in the manual ATI sends. 3.70" pulley is a 9# pulley and with the 3-core intercooler you could see 10 psi if not a little more with a properly tensioned belt. A 3.40" pulley is a 12# pulley...so if you are only seeing 9 psi with a 3" anti-slip pulley you have more problems to solve. The in-line fuel pump is fine and is nearly silent if installed on the frame rail with rubber grommets as opposed to the transmission cross-member.

Pilot(Mark) and Mike Dunn are the best places to get the fuel pumps and advice
Friend's Lightning didn't loose anywhere close to half its boost in Colorado. These ATI setups need a very tight belt, if it wasn't a complete pain in the ass to put the belt on then it's too long.
I use the same belt as the 6 rib for a 4.6 F-150. If you actually use a belt that is the correct length it will wrap around the blower pulley. If it is too short it won't wrap as much and slip.

EDIT: I have the 3.40 pulley on mine.
I have found this out as well for the 3.70 pulley, if the belt was too short the tensioner couldn't push the belt in enough to wrap it around the pulley enough and I was losing 1-2psi consistently.
I found differently. The belt needed to be tight enough that loosening a few of the idlers was required to slip it on. Any shorter and it would loose 5 - 6 psi no matter how much the tensioner was adjusted...even to the point the belts would delaminate. This is with the 3.40" pulley.

What type of belt are you running, I found the gatorback was good, but harder and slipped easier, I went to a NAPA brand and it seems to be softer and grab a little better.
