I'm new to the forum with a 2002 Blazer Extreme with 108,000 miles. I want to get it tuned to improve milage. What are the best plugs, spark plug wires? Any other typical parts replacements?
I'm in California. Can't remove the Cat. Is there a way to improve the cat and if so, what type of muffler will benefit gas mileagee and give me a little tone? Will a K&N cold air induction really make that much difference or is there a wiser expenditure?
Any advice will be appreciated. This seems to be a great place to learn about these rigs...

EDIT : Chevron techron concentrate I've always found to make the most of fuel MPG's with these GM vortec engines

Good to here some ideas from someone who's gone thru the trial and error.
Thanks, Bruce

If you drive in town a lot, get an ecu tune, I was getting high 15 mpg then after ecu tune mid 17mpg. Highway/interstate went down from 18 to 17
