I purchased this tuner on this forum about a year ago as a speedometer calibrator. Once I received it, I found that it was still locked to a vehicle, and I had to pay Hypertech to unlock it. It wasn't much more to just upgrade it to a Max Energy tuner at the same time, so that's what I did. I had my truck tuned with it and corrected my speedometer for my larger tires, and it worked pretty well. The stock tunes aren't earth shattering, but they are noticeable. I recently picked up a Diablosport tuner with the intention of getting a Diablew tune, so this one is on the block. It is unmarried to a vehicle and ready to go for 2006-2013 GM vehicles. The unit comes with the ODBII cable, as well as a USB cable for hooking up to the computer to get the latest software updates from Hypertech. I'm looking to get $225 obo shipped.
I don't have one on my 2015, but I did install the GMPP CAI on my 2004 for a while. The only thing it did was add more intake noise, so it sounded faster, but other than that it didn't do anything. I ended up taking it off as it ended up causing a drone at highway speeds. It was a total waste of money, as are most of the systems, but it did look cool. Our trucks already have a CAI, and other than maybe flowing a bit better, the aftermarket systems are more for looks than anything. For those that modify the exhaust and do other mods, they may help, but you're better off spending the money on a diablew tune if you're looking for a performance boost.
I have a set of four OEM Chevy center caps for 18" and 20", 8 lug wheels. They are in good condition, all the tabs are intact, and they come with the spring clip installed. The model number of these is 9597789. These things are insanely expensive considering what they are. This is a chance to replace damaged or missing caps, or convert from GMC to Chevy (I went the other way). I'm looking to get $80 shipped for the set via paypal gift. I would prefer to sell as a set. The pictures below are of one cap, but the others are in similar condition. Thanks.
I ended up getting a Hypertech Speedometer Calibrator, which I then upgraded to the Max Energy (long story). I installed the regular tune, and fixed the speedo issue. So far my overall impressions of the tune are positive. Other than the speedo, and the regular tune, I bumped the shift firmness up 25%. I didn't change anything else. I might play with the shift points, but for now I'm going to drive it for a couple weeks as is. There isn't a huge difference, but there is a notable difference. Seems to have more pep, but nothing earth shattering. I think the truck is learning how to run/drive right now as every time I drive it it seems to have a bit more snap than the last time.
I love Rock Auto. The problem is with so many options it isn't always clear as to what you actually need. I crawled under the rig and the number is 22811847 so it looks like I got off easy price wise.
My wife's 2012 Yukon needs new shocks. It has the ZW7 premium ride option. I'm having a hell of a time finding rear shocks for it, and searching this forum and google isn't helping. Almost all of the information I'm finding is related to the previous generation 99-06 models. I understand I can use a "standard" shock on the front, but the rear shocks are really causing me grief. On previous models I see where folks swap out the Nivomat shocks for standard models, then swap the springs for z71 springs. I don't seem to be able to find that option for the newer rigs, unless the springs are the same. I'm looking for advice. I need to crawl under her rig and get a model number off the shocks, to at least give me something to start googling with. Either a less expensive option for stock shocks, or a way to convert would be great. Thanks.
I was surprised to see it was off that much. The stock tires were 265/70-17 Duravis, which are ~31.6", and the new tires are Michelin AT2 with a diameter of ~34.1" which is quite a difference. When I first got the OEM 20" wheels, they had worn down stock SR-As on them and I noticed even with them the speedo was off by 1-2 mph. I'm assuming my computer was set based on the size of the tire that was on it when it left the line.
Has anyone used the Diablosport intune i1000? I had 275/65-20s installed yesterday and my speedo is off by ~6 mph at 65 mph (based on GPS speed) and I'd like to fix that and maybe tweak a few other things while I'm at it.
bersh replied to Juniorss's topic in For Sale/WantedDo these just press fit in, or do those springs lock into something? Thanks.
