That or some ETs. I think GMCWantsLS1 runs Hoosiers? My hard NASCAR Goodyears hook up okay as long as I avoid the water box. Get into the water box and then you will be driving over the top of the water your front tires are laying down or the water that you spun off of the rears and then onto the fender wells only to fall back onto the tires again.

I run Hoosiers. They had a 29" tire that would fit on my 8" wide rim and DOT. There might be better choices now.

Hey lance, your sensors could be bad. I have seen them read ok at idle then go whacko when you start driving. What are your WOT voltages? If that shows lean then they probably are bad.

<div class='quotetop'>QUOTE(NITROUS @ Jun 19 2006, 05:18 AM) [snapback]55729[/snapback]</div>I have that EXACT SAME issue. It seems to run fine til the engine gets to operating temperature, then all of a sudden, LTFTs for B1&2 are max'd. Then, it seems as if the engine is running really rich, and is hard to accelerate or idle properly.... I just have to figure out why the LT's on bank1 and 2 are reading max when driving. At idle they stay -0.8 and 2.3. When driving they max out to 25. The funny thing is I logged it at 25 and it only read -0.8 and 2.3 I don't know if HPT is acting up or what. [/b]

Someone mentioned that to me this past weekend, and I think they were on to something. I looked at some old logs that I took, and noticed that B2 o2 wasn't reading any voltage (guess 2nd-hand o2s aren't smart to use). I'm working on my money tree this week to see about some immediate purchases, and o2s may be one of them. Would like to get HPT (I've been borrowing a friend's) to scan & log. That'll be a while though. Friend not happy with me right now... my poor judgement. Me being a little to excited about exhaust & burnout ability (long story).

I'll take a look at the Hoosiers. My problem is locating a 315/35/17 drag radial for a 11" wide rim.
Chris, I'll look at the sensors and voltage, that sounds logical.
1BADC10, hang in there we'll figure it out. You definetely need to get HPTuners with that new engine.
Ryan, I did all that machining on my A/C block and a buddy of mine showed me some A/C gaskets with different thicknesses that will allow you to use a standard block with any late model compressor. There must have been 6 different gaskets that ranged from 1/16" all the way to 3/8". I wish I would have known this before. The sealing area is even a little thicker and will compress to compensate for height differences.
