Long time no post, anyway I was wondering if anyone has tried a ecu tuner/performance module for their 4200 Vortec engine? What are your experiences with power deliver, hp/tq numbers, fuel economy? I think all these areas need improving lol.

Also, for those with lift kits, how has this affected body roll, response, fuel economy?

If you're wondering about lift kits, you're best bet would be to pick MarkMC's brains. From what I know he's the goto guy for this stuff.

If you can't find him here, I know he trolls the offroadtb.com site alot too.

As for the performance aspect of things, pcmforless is apparently the cat's ass for PCM tuning. Check them out! (they're on my shopping list too...)
