Seems to me that the gains from the pulley swap aren't bad, but don't seem nearly as vital as the CAI/tune.


I found that after watching this SCT video which is showing pretty significant gains from CAI, cat back and tune. There's a lot of SCT patting themselves on the back (which they deserve) but once you get into the meat of it, it really sounds like the way to go is CAI and tune.

Guess I'll need to save a few bones up and get a CAI ordered

This is the first one that I got. I wouldn't get the carbon fiber one, or atleast don't tighten it down too hard or it will start to wrinkle/crack. Other than that, JLT is the way to go.

Pulley swap will increase boost... Thus torque and hp as well... I do somewhat agree that cai and tune have the largest impact but would argue that if your going the cai and tune route , why not the pulley too?
As far as whose cai?? That's all just preference on what you like.. As many many tuners have proven they are all in the same ballpark in numbers ... Ford racing, JLT, steeda, c&l etc...

I've used JLT and C&L in the past and been very happy. I'll probably go the JLT route just cuz they seem like the underdog...and I like supporting healthy competition!

You are crazy if you don't do the pulley swap at the same time as the CAI/Tune...... just sayin.

Call VMP and get the kit from them with the JLT 123mm plastic CAI, their pulley and custom tune. You will be glad you did.
