You are correct. I have noticed many flip flops with LMS just in the past 10 months.
With v11 there have been many issues. Dangerously low fuel pressure. They claim theses are out of fuel on a hopped up 93 tune at 60 degrees. So they command for more fuel "because they believe that richer is better". If they believe the system is overtaxed, then why is V11 asking for even more fuel and more RPM?
We also know that running these engines "rich" does create more deposits on the intake valves. LMS for many years said the SHO did not need a catch can. I have believed since day one they needed a CC. The first thing I did to my car was add a CC. Low and behold, LMS now has a catch can for sale, and they believe the SHO could benefit from it.
With V11 there are shifting and trans issues. Some guys reporting it sounded and felt like the trans "let go or exploded". LMS shifts their tuned cars higher (when there is zero benefit ) the car is already way past the powerband approaching 6K. More RPM, more time in the dead usable power zone, more wear and tear under WOT, you catch my drift. I have never had a issue with my transmission shifting, low fuel pressure, or high reving. My fuel pressure stays stable, my shifts are crisp and quick, and my car shifts between 5800 and 6000 rpm. Just because you have always done it that way, and you have access to proprietary Ecoboost knowledge, doesn't mean you are right.
I believe my AJPTurbo tune is better. Period. My car on the E30 tune only (K&N drop in, and 542 plugs) makes more power 391/470 then most full bolt on (intake, full exhaust, T-Stat, LMS tuned) SHO's and that was in 90 degree heat here in Phoenix with the stock heat soaked intercooler. My car is faster then most LMS full bolt on SHO's. 12.56 @ 108, that was with a boost reference line that blew off, and the throttle closing. The car 6o footed a 1.77 and usually goes 112 in the 1/4. So realistically it could have run 12.3X at 112 full weight, 1/4 tank of fuel, and a 250lb driver if things were kosher tune only.
