Well I've considered the long tube headers, just worried about clearance issues. I've got a 2wd so am I good to do long tubes or would mid length be better? I know LTs are best for performance but I'd rather not have to modify anything to get them to fit. The only reason I've really been...

Looking at getting an exhaust put on. Basically looking for economy more than anything but I would really like to NOT sacrifice any low end torque. Now my questions are: X pipe or H pipe? Leave it stock with a different muffler? Do I want more or less backpressure? I'm trying to research...

Well I've now got torque app pro and it shows my temp to be 195. So I guess my dial in the Tahoe is broke lol

I've got a 99 2wd tahoe. I couldn't imagine why the previous owner would put a "hot rod" tstat in a bone stock tahoe

What is the correct operating temp for the 5.7? Right now I'm running at 155-160. I thought it was supposed to be 190-210. Could the t-stat be opening too early? I think I'm suffering some fuel economy because of this. Got 18mpg running 65-70 with about a 15-20mph tailwind for 500 miles and I've...

So basically a direct swap?

Looks like a suburban gas tank is only about 9in wider than the Tahoe's. If it will fit (I haven't measured yet) will I have to get the computer reprogrammed for the new larger tank

well definitely wouldn't be me tackling anything to do with making the truck move so depends on my mechanic lol. If its not at all possible then I'll just chuck the idea.

Just wondering if this is possible and what's needed. My 99 tahoe has the 4l60E and I've found a 4l80E out of a 92 pickup for $300. Would this be possible given the year difference or does that matter with these trannys? Also if this looks like a good deal, what would I need to complete the...

I'd like to have one more seat in my tahoe. I've looked into the little passenger website but $500 is a little steep. Here's my idea so let me know if its safe or room for improvement. I find a center console seat from say a silverado. It appears to have very straight forward feet to be...

Haha see this is what I've been hearing. One says 30, one says maybe 25.

Just a general question here. How big is our Gen tahoe's tank? I filled up from the smaller hash by the E and I could only get 23 gallons in. All specs on the internet say its 30 gallons and the manual says 30 gallons. Saw on here that someone posted there was a lawsuit about the tank...

Hey I'd like to get in on this! 1GNEC13R1XJ558254 [email protected] Thanks!

Can you post some pics

Hey y'all good to finally be apart of this forum. Just picked up a 99 Tahoe LT with 147K and it is extra extra clean. Can't wait to get a lot of helpful of advice from everyone
