Hello Everyone, I have an '03 Chevy Tahoe with a 5.3L v8. I've installed a K&N cold intake system ( definitely noticed the difference), Flowmaster catback ehaust (fairly nice sound slight power increase), and JBL headers (no real difference in sound slight power increase). My friends are saying next to installing a supercharger, my best bet would be to get a performance chip. I see a lot of them on line all boasting HP increases of up to 50 hp. Prices range from $50 to $500 dollars. My question is what chip do you guys recommend that will give me the most bang for the buck. Thank you.

 

Forget the chip and get a tune. Either a mail order tune (Blackbear or Wheatley) or find a local dyno tuner and have them do it. Your waisting your money on a "chip" or hand held tuner. IMO.

 

Thanks for the advice. I'll definitely look into that.

 

a chip is more like a one size fits all item....a tune is more specific.....

 

what's a chip? as far as I know we haven't "chipped" control modules since OBDII?

Look, first of all welcome to the forum. You have a lot to learn and a lot to gain by reading through the archives here.

I also moved your post to it's proper section.

 

I saw an increase of 15whp on the dyno with my blackbear tune on a basically stock tahoe. Definatly worth the money
