    My '02 Tahoe L59 revs WAY too high on cold start ups. Anyone got any ideas?

    After it warms up to temp and idles properly, unplug the iac while idling, shut the truck off, and let it get cold. Try starting it again while cold with the iac unplugged and see if it still revs right up. Most likely it won't rev up. I would guess you have a vac leak. When you start an iac...

    I killed the timing at idle in drive and when returning to idle while coasting to fix the stall push. I am too late on the exhaust thing, but as said above, cats make great mufflers, and they help clean up some stink. Funny story since you brought up the wife and embarrassed. I did a big ass...

    Super awesome! Do another oil change after first drive is my approach. Would have suggested you use cheap oil with a break in additive if I thought of it. You did absolutely nothing wrong, just costs an extra 50 bucks for oil. You didn't do any damage or anything. I put a factory built HKS...

    It would be like installing a control board that uses locating dowels, but you miss with the alignment of the dowel, then when you tighten down the board, the dowels crush the board, instead of the board sitting flush. It's super common and I have done it before. Maybe I say it's super common to...

    Yeah it comes in the cam. It indexes the cam phaser to the camshaft. On a traditional cam sprocket that is non variable timing, you can see the pin on the camshaft go into the sprocket for indexing clear as day. There is zero doubt it is installed because you can see the tip of the pin coming...

    Best to blow them out with compressed air if you have it, unless you have some sort of super skinny ant eater type vac that can reach down 6 inches into a 3/8 hole. Just make sure you wear safety glasses or close your eyes when you give it a shot. No matter how hard you try, coolant always makes...

    I use a welder and Weld a nut on the broken bolts if they are flush or better or slightly below the surface. They come out pretty easy, just need to get onto them. Easy put works as well, but keep a super hawk eye on your angles so you don't go off course and hit water. The easy out way is not...

    That is really good to know! I ass backwards myself into always running a high pressure/volume pump on aluminum engines I guess! Haha! I always run higher pressure/volume melling pumps on engine builds as well, learned something new today thanks! Not sure if you have ever seen the pressure on a...

    I don't change oil pumps when doing a dod delete and keeping the vvt. It is the pressure to work the vvt system that is important, not for the dod.

    Vvt engines run a higher pressure pump than non vvt, that is why people change them out when deleting. That being said, it depends on the mileage on your engine. Anything over 60k, I would change it while I was in there. You can do it without pulling the pan, just need to lower it down and...

    I always choose the stage 2, haven't even done a stage 1. Pretty sure they either recommend the stall for the issue I brought up before about how it pushes through the converter, it was a pain in the ass to dial in the first time, but works well after figured out. That or they just do it as a...

    Just make sure you give the blackbear guy the tsp cam position numbers they supply so he can plunk them in

    Option 3 is a 5.3 liter vvt cam. Either go option one or 2. If you are going to be tuning it yourself with no prior knowledge, it will be easier with the smaller cam, but that doesn't mean it will suddenly be easy, just a little less work to get it to idle properly. If you want to error on the...

    The cam angles are in a large table that references both engine rpm and load, there is full control from idle to red line, there are also separate timing tables that modify spak from the normal base timing based off the various cam angles. That is why you see the peak power finish the exact...

    Here is a back to back test with just a stock cam. The thing about the aftermarket vvt cam is it still pulls super hard down low, much harder than stock does. I don't doubt your 2012 pulls harder than the 2007 if the cam is aftermarket. More power pulls harder for sure. That's not to say it...

    You mis understood me, unless you kept your vvt system and installed a non vvt cam. I have done lots of vvt deletes, it used to be all I did automatically for years. I meant there is a reason people don't put a non vvt designed cam into a vehicle and still retain the vvt system. A vvt cam is...

    There is a reason you don't put a non vvt cam into a vvt controlled system. If it was as simple as advancing and retarding a normal cam, it would be one thing, but there are many many hours spent on development of the l92 vvt cams to take advantage of the technology.
