Engine mods???

[03_gmc_yukon]

Hello there,

I'm new to this forum and not sure how to go about this but..I have an 03 gmc yukon I picked up a few months ago and haven't done to much it except replace the motor because I was being a dumbass and threw a rod.

The motor is a 5.3 with like 2500 miles on it haha and already has a mild cam in it, not a lopey one but you can feel the difference. Intake, muffler and some royal purple is about all i've done since then.

Anyways, I was wondering what performance mods I could do to make it quicker and benefit from it and what not, anything at all would be helpful..

Thanks

In our vendor section, the company is called Black Bear Performance. Justin will tune your PCM, can adjust your shift points etc in order to free up some power can give your ride some more giddy up.

Any other suggestions?

I would go the long tube headers and e-fans route then maybe a set of pullies.

stock tires? Since it has a new 5.3, get some LPP headers, comes with ORY for around $450-$500. Then have a tune, delete the 02 sensors. If you went with bigger (taller) tires, check and see what gears you have. And a TB stall would really help as well. You can get one for under $200.
