I am new to the site, but a friend recommended it and he said most of you on here know your stuff when it comes to trucks. So I have a couple of questions for all you. I have a 2002 Chevrolet S-10 w/a 4.3L Vortec. I am wanting to do a performance tune on it but cant seem to find any place worth looking into for what i want. Any suggestions? I am also wanting to put different gears in my rear end...I think 4.10 would be to big, so any suggestions on that as well?

 

K&N filter, cold air intake, and a good tune-up (new plugs/wires, oil change)

 

i have a 98 jimmy with the vortec 4.3. i would do a CIA, throttle body spacer, MAF, a set of headers, and a magna-flow exhaust. and they have a plug and play tunner. all this could be found as auto every thing . com. as for the gearing, i know the 4.10 is not to big for the truck asa buddy of mine has an s-10 with 4.10s. but i wouldent go to much bigger than that.

 

No throttle body spacer or handheld tuner, get a custom tune

take yoru pick of wich tuner you would like

 

I'm saying dont get a Throttle Body Spacer or Handheld tuner......TBS's dont do anything on that engine and a handheld tuner is a waste get a custom tune

 

TB spacers are paper weights. They don't do anything on vortec V8's why would they work on the V6?

Custom tune is the one mod that will give you a bigger gain than any CAI, exhaust, and headers combined.

Handhelds?

Get a custom Tune!!!!

 

anyone know of anyone who does a good tune on a 4.3?

 

Bet Nelson's got something
