    Burb shakes when braking - INTERMITTENT

    It's most likely a warped rotor. I have received plenty of bad "new" parts in the past. Most recently I had codes getting thrown that lead me to replace both the MAF and MAP sensor and the new MAF from GM was faulty. Drove me crazy for 2 weeks until someone I know offered to get me another MAF...

    L83 5.3 with 7500rpm build - Suggestions?

    Yes - the Whipple kits all come with a water cooled intercooler kit., I even opted for the high volume intercooler pump, and long-timing relays so the pump runs another minute longer after shutting down the truck - kinda like a turbo timer. I also removed the active aero shutters from in front...

    L83 5.3 with 7500rpm build - Suggestions?

    I have some time to decide in which direction I wish or should go. Good education on block stresses - didn't think of that. Same for valve seats. The L8P is a much more economical way to go and will be well over 600wheel, even with the 8lbs pulley. I just feel like that short rpm range is...

    L83 5.3 with 7500rpm build - Suggestions?

    @Joseph Garcia @pronstar I've been considering the crate motor as well but my issue is the short redline. I find myself hitting the rev-limiter in 2nd gear during most AutoX events. Courses are usually short, with lower top speeds so I keep it in 2nd the whole time. With another 1000-1500...

    L83 5.3 with 7500rpm build - Suggestions?

    L83 5.3, Whipple 2.9, LTRs, full exhaust. 118k miles, stock bottom end. Owned since new - well maintained. Looking to refresh my motor over the winter. I would like to have a 7500rpm redline with a broad power curve. Looking for midrange power for track and AutoX. I'd like to see 550+ to...

    HP Tuners Modifications for GM Trucks.

    Subscribed. Outside of changing wheel and tire size I'm too afraid to try anything else. Since I already had a remote tune done, the truck is running properly with my mods. I will have to wait to either get an updated tune from a reputable remote tuner so do a file compare when I bring it to...

    How are your 10 speeds doing?

    You had to get the 6.2 in order to have the 10 speed for 2018-2020 K2XX platform. All T1XXs come with 10 speed. If my recall is correct (too lazy to google), the '19s & '20s the 5.3's came with the 8 speed only. All 10 speeds have issues but the later versions seem to be worse. The fix is a...

    Power steering driving me nuts

    Not sure if the dealership you went to has a "master tech" on staff but I've had this before and a "re-learn" cleared my issue. All K2XX platforms and later (2014 - current pickups | 2015-current SUV) have electric power assist. Our owners manual (Mine is a 2017) states power steering fluid...

    What do these codes mean and how do I fix it?

    I thought all K2XX platforms were gascap-less? Were the earlier years different?

    2016 Yukon XL Transmission Failure

    I personally would recommend the rebuild route. Warranty work is nice but a reman or replacement from OEM is going to reset your clock at 0 and start over again. I prefer the "over build it to last forever" route. My trans build part list is attached. Probably overkill for you cause this is...

    How many miles is too many for used?

    Thats OK but I would look to replace it with an aftermarket unit. If the OEM TC was replaced with another OEM TC, you aren;t avoiding the problem, you are just delaying it. Yes but there is a major defect in the valve body. This goes for both the GM and Ford units. (10Lxx and 10Rxx) Remember...

    How many miles is too many for used?

    The key to surviving the AFM disaster is frequent oil changes. Especially on the newer K2XX platfor cause the DI motors seem to burn more oil as DI's inherent nature. Thats evident on any MFG using DI now. I've stood on my soap box about this a few times before but this push by MFGs for...

    *Solved* Intake Air Temperature Sensor

    Codes cleared. Don't know why. Maybe cause I let it rest over the weekend? I dunno. I checked ODB DTCs on Friday (05/15) and P2227/8 were still showing permanent even after clearing....after multiple drive cycles. Someone I spoke with stated there could be a vacuum leak somewhere. SO I...

    *Solved* Intake Air Temperature Sensor

    OK I went out for a ride and pretty much followed your suggestion to the letter. Attached are the DTCs before my ride. I grabbed screen shots from my ODBLink MX+ before I pulled out of the drive way. Before the drive I swapped out my ODBMX+ for HPTuners. Someone on that forum wanted me to do...

    *Solved* Intake Air Temperature Sensor

    Someone replied to me on HPTuners forum: "Both of those codes are actually for the barometric pressure sensor. The barometric pressure sensor is in the MAF sensor unless for whatever reason you have a breakout harness. The 2227 can be a calibration issue as in the code can either be turned off...

    *Solved* Intake Air Temperature Sensor

    New MAP installed - all codes but 2 gone - P2227 and P2228. Both of those lead back to MAF or MAP. Could be a bad sensor. Don't know. I cleaned the connectors with Deoxit and used some dielectric great on them after cleaning. Cleared codes and they came right back. Spent the better part of...

    *Solved* Intake Air Temperature Sensor

    MAP sensor on the whipple is located at the back of the lower intake manifold. Absolute b@tch to get to but I managed to get it off. Followed this video: Unfortunately for me, my gen 3 Whipple uses a 4 bar MAP sensor like the ZL1 so the MAP sensor I purchased is useless. So I am on the...

    *Solved* Intake Air Temperature Sensor

    @Doubeleive Just watched the video - I am getting the same readings. Gonna try and replace the MAP tonight if I can reach it. Funny thing - that guy is located in Jersey so I just reached out to him to see if he is available and his rate. Hopefully he responds.

    Cuts off when turning right (Intermittent)

    You said you CHECKED the grounds but did you REPLACE the grounds? I've got multiple posts in this forum and other about this in my truck. The truck would literally "reboot" where everything would shut down and 2~5 seconds later it would come to life. This happened a couple times to me at 50+...

    *Solved* Intake Air Temperature Sensor

    I posted in my own thread but my google search came back with this one. Hoping I can wake up the troubleshooters that were in this thread or others that really know. @Big Mama @Fless @Doubeleive @Joseph Garcia From left to right we got 4.7, 4.7, ground, a flakey ground, 12v, 4.7, ground...

    Throwing Codes - P0097, P00F4, P2101, P2199, P2227, & P2228

    2017 Burb 5.3/6L80 When I started my truck to leave work yesterday (Tuesday), I got a SES. Codes are P0097, P00F4, P2199, P2227, & P2228. A little research lead me to believe it was the MAF going bad. Kind of expected after 117K and a whipple 2.9 sucking on the intake for 65k of that 117k...

    Big 3 Upgrade

    You can easily add a couple of fresh ground cables using 8 gauge wire - preferrable Oxygen Free Copper (OFC). You can pick that up at any local car audio shop or even best buy and order a couple of quality copper ring terminals. I added an engine to firewall, firewall to frame, frame to engine...

    Track Day!

    I just ordered a Dragy so I can start seeing what it can pull on G's etc. There's nothing left of the OEM suspension. Everything has been replaced. Belltech 2" drop spindles Belltech coil overs - front (dropped the front another 1 3/4") Mevotech boxed aluminum A arms with poly bushings...
