I’m absolutely not interested in bashing a well respected tuner. I have faith that they’re as good as anyone else out there. They have proven results for many happy customers. Absolutely look them up if you’re considering a tune.
So far, I’m just not thrilled and I want to share my experiences. Any feedback is welcome. If you think I expected too much or didn’t do enough homework, I can handle the criticism.
So I detailed my regrettable adventure of swapping in the Ford Performance 4.09:1 ring and pinion on mg over in the drivetrain forum. It has been a series of headaches from well meaning people with bad info (including me). I take the blame for assuming that the 2018 cars were basically the same as my 2020.
I didn’t want to do the job myself. I got a decent quote and was told by my Ford service dept that the job and correcting for the ratio would be no problem...they were wrong, of course and handed the car back to me with a shrug and a bunch of DTCs.
As it turns out, Ford has not (as of the time of this writing) released their official ProCal kit to accommodate these gears in 2019 and 2020 cars even though they will sell them to people who own these model years. Lovely. This kit is the ONLY official way to make the gears work.
So as you would guess, without the calibration, the car drove like hot garbage. The weird rev hang behavior drove me nuts, no rev match feature, no cruise control, etc. The gears we’re working great though and it despite the tune problems, it pulled nicely.
So I couldn’t wait for Ford’s official fix so I reached out to Lund Racing who said they could make the ratio correction so the car would drive properly and specifically that they could restore the rev match feature. Great!
I ordered up the NGauge and the tune. The tune showed up in my email super fast, the NGauge took a little longer. It arrived on a Friday afternoon (a week and a few days ago). I promptly installed the device and uploaded the tune and discovered that the tune didn’t work at all. No difference whatsoever. So...I had another weekend of driving a screwed up car.
The car threw codes which I sent to Lund. The reply was that the tune was fine but the codes indicated a neutral position sensor switch. Lund rep was sure that something came unplugged or the harness was bad...a very unlikely scenario for a brand new car but just the same, I spent hours trying to find a diagram for the location of the switch to see if just maybe they were right..but it just didn’t sound right. The trans was never touched. The car worked fine before the tune. Well it turns out that the same code can indicate a generic drivetrain malfunction (like having the wrong gears). Thank you to BAMA Performance for helping me figure that out. No shit.
I wrote back, asking Lund to double check the tune and reminding them that 2020s were unique, etc and sure enough they came back with a tune revision that worked. Mistakes happen. No problem. Let’s get on with life and enjoy the car.
For the past week, it has been a mixed bag. No DTCs, the gears still feel great but the 91-93 octane performance tune made no noticeable difference to the sensation of power.... I have even had a few moments when rolling onto the throttle, the car fell kinda flat. So...yep. those are totally subjective observations. Maybe my butt dyno is just out of calibration. So I collected a data log to see if they could just make sure all was ok.
The bigger problem is the rev match feature. Yes, it mostly works now...but it consistently overshoots by a couple hundred RPM which can be annoying when down shifting among the higher gears. Instead of the seamless “heel-toe gear changes The car lurches or requires slipping the clutch just a little....disappointing and annoying, especially since I was told specifically that this would be restored.
I went back to them today to send the logs to make sure all was good and to see if they could tweak the tune to fix the over-rev.
The answer was no.
The tune looked fine but the car isn’t making great power because I’m on pump gas. Ok...
The rev match feature can’t be addressed at all. They don’t know how to fix it. I was told that they tried messing with it in Alex’s car (is that the “Yolo Douche Bag” guy from YouTube?) and never got it working like stock again.
Soooo I paid $630 to correct one parameter in the PCM.
Was I expecting too much?
Everyone has been prompt and professional. They seem like good folks. It’s just that the product fell short of what I expected and I don’t get the sense that they care all that much.
