I recently did a dod delete on my 2007 suburban. 6.0 200,000 miles. I thought the problem was the afm lifters being that there was a tick at highway speeds. I only had a tick at highway speeds. If I drove on the street I would never get the noise. As soon as I held a steady speed on the highway I would get what sounds like a lifter tick. The dod delete work was done by a Preformance shop. I do not think that dod was the problem. If I hold the throttle steady at 2000rpm while in park I can get the tick to come on. After I let the engine idle about 2-3 minutes the tick goes away. As soon as I hold the rpms back up it will come back and repeat the process. No loss of power while this is happening and no other sounds. Oil pressure is about 10-15 at idle and close to 40 while on highway. I would greatly appreciate any help.
This is my first time posting in this forum!!
Just bought a DiabloSport Itune I3 Platinum Programmer.
I am looking for some decisive direction as well as suggestions on the best parameters for tuning my truck with the I3 Platinum.
Specs of Truck:
2014 Silverado Z71 LTZ 2WD Crew Cab
Rough Country leveling kit installed
33" x 12.5" x 22" Nitto Terra Grappler G2 A/T tires
5.3L Ecotec flex engine
K & N Cold Air Intake installed
Gentle 46k miles
I RUN 93 OCTANE IN THIS TRUCK
Being a 2 wheel drive (It Does have the Z71 package, Rancho shocks, etc...) Obviously it raked in the front.
First thing I did was put the K&N CAI on and it was like a rocket in Manual 5 gear mode, when I shifted through the gears myself.
After leveling kit and 33's with aggressive tread, it was complete garbage. No power, confused shift points, almost like missing. Just a hot mess.
So I bought the Intune I3 first, rather than switching to a 4.10 gear (which I may do later).
Already turned off AFM and that was immediately effective. Also, 15% throttle boost.
Can anyone suggest the best parameters to make this bad boy get up and GO!!??
I would like to know if there is a good idea on what ECM and TCM adjustments should be made to not only get that stock power back on 33's. But also get good fuel economy.
The standard Diablo Flex, Jammer and 91 tunes don't seem to help a whole lot. Still bogs down and takes forever to get through 1st and 2nd gear. Anybody know about these tuners on a 14 Silverado with 33's?!?!?!
I have an RX Speedworks catch can that i had installed on my 2016 Sierra. It attaches using the bolt for the brake fluid. Has the clean side separator that I used as well but not included in the pics but can provide more pics upon request. Will work on other vehicles. My price is obo shipped. TIA. https://www.rxspeedworks.com/product/gmc-sierra-oil-catch-can/
Like the title says, I am wondering if anyone has any experience with the AFE SCORCHER PRO Performance Programmer. I have a '14 6.2, and am looking in to tuning options. Seems like the regular Scorcher has a good reputation in the diesel crowd, but have yet to find a single review on the newer units.

Just got a new 2018 Sierra with more bells and whistles than I've ever seen in a truck before. Sure learning a lot on these forums.
The catch can thing has my interest, I never even knew that was a problem, never had a direct injection vehicle before.
I'm looking under the hood on this thing and although it is difficult to see much it looks like there are two PCV valves, assuming that's what I think I'm seeing. They are right up front of the engine, one each side, with short tubes going into the intake air plenum. See attached photo of the front left side of the engine.
So question #1, are two PCVs what I am seeing?
Question #2, if so then I need either two catch cans, or one that does double duty, right?
I'm a little confident that the answers to my questions will be yes (still appreciate confirmation though) and if so this will be a plumbing nightmare. This truck has the eAssist which means the only open space for a can is the front left corner where the battery used to be, on eAssist it's up in the back right corner of the engine bay. And, there is no room at all left in that part of the engine bay, it is packed.
So I guess question #3 is, anyone come up with a creative way of solving this problem, besides hoses all across the top of the engine?
Thanks in advance for responses.
