I am a newbie looking to increase the performance in my 02 5.3L. It is a daily driver but also my tow vehicle. I would like to get better towing performance as well as overall street performance. Where do you suggest I start? I have a throttle body spacer, K&N replacement filter, and a flowmaster already installed. Thanks

 

Budget???

 

some sort of pcm enhancement, either a handheld like the Predator, Crane/Vinci, or something like that. Or.....you could go the way of a mail order tune from any of out sponsers, Waitforme;Nelson, etc. Or do it all by getting HP Tuners, or EFI Live. Any way you look at it, there LOTS to be gained in tuning.

 

Haven't gotten to the budget yet - just getting a feel for what's out there. I prefer to keep it modest. Once I find a starting point I'll have a better idea.

 

CIA, e-Fans, headers, tuning, and the free mods......

 

Tuning

 

New to this.....CIA?

 

headers, cam, and a tune. put the spacer on your desk atop some papers, it'll work better there

 

I'm thinking he meant to write "CAI" meaning cold air intake, putting an aftermarket air intake manifold on, such as K&N

 

What kind of weight are ya pulling? Sometimes better towing and better street performance conflict each other.

Everything I have in my sig marginally helped both performance and towing ability (I tow 5400#+ on weekends).

If ya got money to burn, just slap a radix and built tranny in, and call it done!
