i already have an airintake and magnaflow cat back exhaust. what should be my next mod for performance?

1: e fans

2: under drive pully

3: xcal 2

should that be the route i should go? or would you suggest different.?

02 4.6 super crew btw

thanks mike

 

Go for the XCal2 next because it’s the *biggest bang for the buck* mod without exception.
You’ll also feel the most seat of the pants performance difference with the XCal2

 

i second the xcal

 

I third the Xcall-II.
You just won't regret it! I have yet to run a 93 octane tune and I love it!

 

Hi 024drscrew,

Absolutely, I agree with everyone else - custom tuning in the XCal 2 is what I would do next.

That's going to get you more power, much better shifting, the top speed limiter removed, etc. And the tuning can always be updated via email if you do other mods in the future that actually affect the tuning.

The underdrive pulleys & e-fans are *great* mods, don't get me wrong, we like to see them on every vehicle to reduce those parasitic losses - but the tuning will do a number of things for the vehicle, so I would do the tuning next, and then on to other mods like the pulleys & e-fans, etc.
