    Ring & Pinion Pattern Second Opinion

    By too deep, do you mean to deep in the housing or too deep into the gear? Backlash is at .007

    Ring & Pinion Pattern Second Opinion

    I have seen a few videos where they suggest the pinion movement, changes the depth of the pinion in the teeth of the ring (closer to the face or the root), Also that is more important than the toe/heel location. I was under the impression that being a littel closer to the toe allows for the...

    Ring & Pinion Pattern Second Opinion

    I am looking for some input on this. I have gotten some mixed suggestions so far. I have done quite a bit of adjustments and so far this is the best pattern I can come up with. It is new gears and all new bearings.

    Catalytic Converter(s) Question

    It may not matter other than the positioning of the converters being different distances from the engine. Like I said it is about 20" difference. I guess I was wondering if the distance may effect temperatures and if someone had experience with this system. The 2500 Yukons & Burbs do have a...

    Catalytic Converter(s) Question

    I am getting very lows 10s in the city. I asked a group of 2500 6.0 Yuks and Burbs and they were getting mid 11s. I would have opted for the 8.1 had I known the mpgs with this truck were not that far off. I dont know of a shop with those tools. I dont really want to take it to the stealership.

    5.3 Style Y-Pipe on a 6.0?

    This is similar to what I have except it has 4 cats (California Truck). My truck is a 2500 Yukon XL, and I havent found that the exhaust parts interchange, but I could be wrong.

    5.3 Style Y-Pipe on a 6.0?

    I have the truck in Florida, but previous owner had it shipped from CA. However, I took it to a muffler shop just to see what they might suggest, and the manager seemed to think it wasn't an issue if there were no codes. So much so that he really didnt even want to quote me (I respect that he...

    5.3 Style Y-Pipe on a 6.0?

    There seems to be a lot of options - as far as upgrades or replacements for the single inlet style. There are hardly any for the dual inlet style. I thought it might be more common since (I believe) all the 6.0s have the dual inlet style.

    I sent one email to the "contact us" from your homepage and then I replied to a email thread that originally had the tune info. It isnt urgent, just thought I would I post here to see if perhaps someone else had a similar question or knew the answer.

    Catalytic Converter - Tune Questions

    Hi I have my Yukon tuned by you guys and I am happy with it. My question is; My mileage has been suffering regardless of driving style and tune/fuel combination. SO I was checking my cats with a IR gun and one has more heat before at the inlet and lower after on the outlet. I know that is...

    5.3 Style Y-Pipe on a 6.0?

    This is what I am working with. Its a California 4 cat set-up. I will be taking it in for an estimate on two hi flow cats and maybe the muffler.

    5.3 Style Y-Pipe on a 6.0?

    Well, I think I have a bad cat. The exhaust system on my truck is a 2 into one muffler style. One of the cats is part of the muffler, and that is the bad one. I cannot find a replacement for this muffler/cat combo anywhere, so I was considering just swapping out the whole system to the 5.3 style...

    5.3 Style Y-Pipe on a 6.0?

    Catalytic Converter(s) Question

    I have a 2500 Yukon. The exhaust is quite a bit different than 1500 models and appears to be different than 2500 pick-ups. The cats are positioned at different lengths from the engine by about 20" In any case, I have been questioning my fuel mileage recently and thought to check the temperatures...

    Roadmaster Active Suspension - Helper Springs? 2500 Yukon

    I have a 2500 Yukon, I was recently made aware of Roadmaster Active Suspension kits. Apparently these kits keep tension on the rear leafs so they stay in their original arched position. And as more load is added the more they arch the spring. Reports are they actually make it a more comfortable...

    Alternative Side molding?

    I have a feeling this has been discussed, but I want to remove the large trim from my 03 Yuk XL, but was wondering if anybody has substituted it with a smaller trim from another vehicle that looks descent.

    Idle Vibration after tune (BBT)

    Finally got the new file loaded. It runs without the vibration. I guess most of these have a little miss or shake at idle when stock. The RPM increase is supposed to eliminate that. I guess my truck is a little different - who knows. There was definitely a problem with the revised file I had...

    Idle Vibration after tune (BBT)

    Well, I am a little miffed. I sent in a log file back on 8/22, I finally got a new file back around two weeks later 9/6. I dont know if that is normal turnaround. I guess I was expecting something a little quicker to just drop back down the idle. Perhaps it is a little more complicated?? In any...
