It was wanting to make big power down low. The fuel and torque curve went flat at 3600 RPM and it was seeing 520/521 at that point lol. My tuner said there’s well over 800rwhp in the car at 19-20lbs. 1000 on 25-26lbs. It was ready for it that’s for sure...as was I. Disappointed but not discouraged. I’ll have it back there in a couple weeks. Wish I had some cooler news for all you faithful bros but that’s kinda how it goes I guess in this game sometimes.What did she make before it cut out?
After discussing things in depth with my tuner we’ve decided to swap a short runner intake on the car while the injectors are out. We feel we like we are going to lose power up top due to not having enough camshaft to wake the current intake up in the high rpms. Don’t worry...it will be custom. Wasn’t an easy decision but I want this car to perform as perfect as it appears.Looking forward to more details and progress.

Correct, the MMR intake is performing incredibly well down low but it’s causing the car to lose steam up top where the turbo does it’s best work. This car was built with rolls and highways in mind so I don’t want it to fade out backWow, tough choice. I thought the short runners were for top end and longer for bottom and midrange? Maybe I read it backwards, I am tired and just finished a long drive

Hmmm, Interesting theory. Precision spec’d this turbo specifically for my setup. I’d be pretty bummed out if that were the case. We’ll soon find out!My worthless $.02... falling off up top could be the turbo choice.
That unit is known to choke up the exhaust on coyote motors. I know this is not a coyote, but it’s similar enough with the work youve done it’s worth looking into.
You might need to switch it up to a borg Warner with a larger hot side.

Check out this video... the 7675 doenst flow enough on the hot side for Ford 4 valve motors in my opinoin and many others.
The intro is hokey but ffwd to about the 2:00 mark and he describes the differences. His car was falling off HARD up top and actually not making the amount of boost his wastegate springs should have allowed. I.E., he had 7 o 8 psi springs in the gates and the car was only makin 5 psi boost because the hot side of the turbo was choking the motor so bad. Some of his other videos explain this as well.
I believe this is the same exact turbo you are running... the Precision LS series 7675.
The intake manifold you have is a beauty and i seriously doubt its the reason your car is lacking up top... worth looking into sir!!
