Anyone know of any options for retuning the little brother engine. Ive done a catback and k&n drop in filter and trying to think of other things to do for better street performance or gas mileage. I almost never haul a trailer.

 

I jumped in on one of the Troyer group purchases on here back in 05' and got an XCAL2 with 3 custom tunes. The tunes really woke up this lil 4.2. The truck is tons more fun to drive now and it just seems to operate so much smoother. I would stongly recommend looking into custom tuning.

 

What year 4.2L do you have? We have a few different options for the smaller siblings.
