Neither. Its based on measurable facts with 2 sets of empirical data: 1) the amount of Boost and Load Actual displayed (Cobb is obviously higher). 2) The drag strip shows a best run of 13.7 @ 100 on the MPT tune and a best of 13.3 @ 102 on the Cobb tune. All with very good 93 octane fuel...

HAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAAHHA.... breathe...HAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHH. Oh man, that hurts...

I had a "technician" at a state inspection facility crack a windshield and not tell anyone. When my wife went to pick up the vehicle, the manager said it failed due to broken windshield! Wife looked at it and said No Fu*king Way it was like that before it was brought in. We're not idiots...

Looks like an internal stress crack to me. It isn't real common, but it does happen in windshields as they are glued to the structure and stressed as such. Sort of like a sunroof or side window spontaneously cracking into thousands of pieces. Check the warranty pamphlet because some of these...

Do this ^^^^^ for best results. You won't be disappointed. The Cobb supplied tunes are really just a very good, safe baseline tune with a bit more power/torque than stock, but still 100% safe. Then the Cobb Pro-Tuners (like Goosetune and a few others) step in and raise the power across the...

The hard 1-2 shift is indeed an MPT programming quirk. It isn't terrible, but can be annoying when driving in relative traffic. If you're in 2WD and poke it hard it will bark the tires on the 1-2 shift as well. If you simply reflash the tune, it will work great until the trans adaptive...

I'm thinking the bolts are like practically every major fastener on a new Ford product and are one-time use torque-to-yield. If so, the dealer must replace them if they are loosened to "align" the rear axle...(?) As for the OP problem, vehicles with a live rear axle are practically never...

I don't think it's a "late" build as the build date is Jan 3, 2018 and I bought it on Jan 31, 2018. That said however, I don't know when the MY18 production started, so it could be "later" in the MY cycle. Mine has the "silencers" in the ducts.

My 2018 is the same as your photo of the 2019-20...

Likely 71 deg Celsius, which is 160 deg F. The stock TS in my 2018 was 95C/203F...

Yeah, I can understand your feeling that way based on the feedback posted by the folks that have experienced the problem. However, you should also know that this problem doesn't affect all the 3.5TT HO EB Raptors. Not a lot of consolation to those that do have the problem BUT, when fixed with...

Yeah if considering increased performance/power, then an aftermarket tune for the ECU and TCM (engine and Trans) from Cobb or MPT is the most bang for the buck. In OTS tunes, the Cobb makes the most safe power plus there are several tuners that can get you more from the Cobb. There rest of...

Yes, gearing makes a huge difference in measured performance. My point is that you need not replace the ring/pinion gears for lower gearing. The best way on a the Gen2 like ours is to change the tire diameter. Using separate sets of tires, you can change the overall ratio for just about any...

This ^^^. If you just rev it up there’s no load demand, so no boost. You can floor it and rev it to the rev limiter with no load and see no boost. There must be significant exhaust flow (load) to spool the turbos.

What’s your goal with a ratio change?

So, I installed a 180 degF t-stat in my 2018. Note the oem t-stat removed is a 95”C” temp which is actually 203F which is a most common temp in all the vehicles in the last decade or so. The oem target temp is 210F so the fans DC is setup for that value. I tweaked the target down to 195F and the...

LOL I thought I had a bad check-valve in my 2018, but it was the solenoid itself. I now have a “spare” check-valve. As for the PENis holder, it’s useless for a PENis but if you stretch a rubber band or similar stretchy cord across them you can keep your registration/insurance under it so it’s...

LOL Well, did you learn anything?

If you also have the Cobb TCM setup, you can load the Cobb Sport TCM tune and run in 4A all the time. In this setup, you're always in "sport" and 4A every time you start and always. You can still set the truck drive mode into Sport mode for the few additional features like holding the gear...

I had it at the drag strip last on 03/07/2020. Just a couple months ago. I also have a Draggy and the AP that tells me almost every weekend that there is no loss of performance. I drive it daily, so... IMO, the folks that have plug problems, misfires, etc. are running shit for fuel.

The only engines that NEED catch cans are DIRECT INJECTION (only), especially the turbocharged versions. There's tons of info on it in every brand forum that run DI engines. It's a FACT that Ford has recognized and several other makes have instructions on how to clean the valves as a result of...

I have the HPTuners tuning setup, but I switched over to Cobb when they finally released their products for the Raptor. I use the Cobb AccessTuner software and the AccessPort. I haven’t tuned a GM ECU, only Ford and Mazda. The overwhelming majority on this forum know nothing about tuning...

I just went with 15 ft so I would have plenty of slack to route the wire anywhere I wanted. I came up the driver side following the brake lines mostly, routed over to the passenger side behind the firewall insulation to the up-fitter switch wire. I use a switch to activate them rather than the...

@Oldfart If there’s a chance you may return to that dealer for any future purchase or warranty service, then you should take advantage of the GM’s effort to make you happy. That said, you will likely be required to “adjust” your previous survey to improve their result. “I” would NEVER accept...

Yes! 170 is a bit too cool for the interior heater to work well. 180 is perfect IF you set the various grill & intercooler shutter, fans, and several other cross-over points in the tune to account for the cooler engine temps. The factory Desired Operating Temp is 210 degF
