It held the power for like 25k miles-ish. It never "broke" , just started slipping. It's not a tuning issue. Its rated for 700NM / 516 torque. I was making 530WTQ when dyno'd on a hot day on a mustang dyno. MCT is rated at 1000NM / 737 torque and has a few additional clutches and brakes in the packs. I'm not upset, this is normal modded car stuff... if you actually drive your car. Modify outside of factory tolerances and things will wear out faster. I did mention the 3 power steering pumps or driveshaft either.

Back to the point of this thread. I don't understand how excessive crank pressure was never an issue until the messed with the heads. Either these guys are straight up hacks and scam artists or there is a lot of miscommunication and confusion happening. Good luck with your lawsuit.

I had a base map from Eurocharged for a stage 3 Weistec supercharger with weistec pulley. Reason why I had Eurocharged tune and not Weistec, replaced ECU with a new one and Eurocharged was a local shop. Before the car was switched back to just headers and no supercharger, Eurocharged reflashed the ECU for their tune with just headers and stock injectors, and that was the tune that the car had on it when it was started up the other day and all of this happened
