Squeal under wot shift

[V6junkie]

So changed my MPT 93prx shift pressure from 15 to 20% and was doing maybe 35 or 40 in sport and floored and when it downshifted I could hear what I thought was a bealt squeal from up front and it's done this from a stop also any ideas or is it tire chirp and I'm being paranoid lol

Dude, I too heard the same most probably belt squeal for engine bay yesterday for the first time, for sure for me its coming from engine bay. :doh: I also wanted to post the same todayvbefore I reach out to MPT. Glad u did but I havent made any changes to shift firmess . Its just the MPT93PRX tune with rev limiter changed to 5000k

it would be nice if you were able to get a video of it so we could also hear what you are asking and make an informed statement

No mods on my engine and I have serious belt squeal in WOT shifts. Especially in sport mode. It's done it since day one.

Totally normal. Some techs say it's moisture , we have 100° summers here so no..
I just told them when the flywheel breaks, I have this issue documented. Lol

But yeah mine squeals all the time and so do older Ford 3.7 engines.

At WOT in 2 Gear again I heard a bad squel from the engine... some sort of belt slipage ?

Mine does it on the WOT 1-2 shift all the time. Only sometimes on the 2-3 shift.
