ECU Upgrade - 2002 Chevy Suburban - CarForum.net - Car Forums, Automotive News and Community

I need to find a good ECU chip for a 2002 Chevrolet Suburban. It's a LT Autoride with the base engine. Looking for the best torque upgrade. It's for help towing a boat.

What is said base engine, and why do you need it in order to tow a boat anyway

base engine is the 327cu-in. Apparently there was a bigger one.

We just want the best torque we can get out of the Suburban. When we take it to Lake Billy Chinook, going uphill out of the canyon, we top out at 30MPH... little slow and dangerous...

I know it exists, I just need a recommendation

It's a 20Ft (2006?) Boulton with a 4-foot expansion (what is it called?) with a 150 Honda Four Stroke outboard. It's rated for a half-ton truck, and the suburban fits that.

should be good. is it a Skiff?

KSIMP88 · 08-25-2009, 09:29 AM

no, something else

**Mike** · 08-25-2009, 10:49 AM

Yeah that'll be a 5.3...in all honesty that should have plenty of balls... sure something isn't wrong with the truck?

Yes, it's a big slope, LOL
