S331 Performance Upgrades?

[S331#18supercrew]

I have a 2008 S331 Super Crew Bumper Sticker #18... I want to make this beast faster, I Need Help in getting information on parts that fit my truck. I need info on best pulley for the charger n help on how to get a custom air intake of 100mm as I was told by Jdm that I needed. Currently it only has cold air intake, shift kit on the transmission, tuned by Jdm... Thank for the help

Welcome to the site first of all. I'm getting my tune from JDM tomorrow so I'll let you know how I like it. I've heard they do kind of a conservative tune so you might want to look into a custom dyno tune if you have someone that has tuned the 3 valve 5.4's. I've seen guys run a 3.0 pulley and have pretty good success but you'll need an air intake before that because you don't want the maf to peg. JDM is a good place to start for information. Hope this helps

I have the JDM kit and it is worth every penny. Installed it myself in about 5 hours.

Jdm no longer sells the kit's :/ so I'm searching for other options.....

I know troyer performance sells a kit too. I talked to the guy there and he seems to know his stuff. And it is a little bit cheaper. So give them a try.

I heard the problem with Troyer is the tune. He doesn't know how to tune these trucks

I will say - Troyer tuned my 2006 F150 and was awesome. No supercharger of coarse.

Man, these trucks get around alot. Yours was originally in Tampa, FL.!

I've got 3.0 pulley on mine from JDM, cold air intake, Long tube headers, no cats, true dual exhaust with H pipe and high flow magna flow exhaust. Gear changed to 4.56's. with a rather conservative tune I made about 450 on the dyno. Bone stock they make 360 on the dyno

I own bumper 153. It has a tune but I don’t have the tuner. It’s got headers and a CAI not sure which pulley. Has anybody owned this truck?
