Dyno After GT350 Intake Manifold Install

[TX5OH]

Had the car dynoed at two different places. The first pulls were in December before I got the GT350 intake manifold. It was on a Mustang Dyno and the shop gave me "dynojet" comparison pull and one with the Mustang Dyno settings. Regardless either one showed I was making insane torque and a few on here questioned the validity of it. So after I installed the new manifold I had it dynoed at the same shop for a comparison to the gains and I also went and had it dynoed at a different shop on a DynoJet just to see if it was just a happy dyno. Unfortunately I didn't get a pull on the dynojet before I did the swap, but here is the before on the Mustang Dyno with "DynoJet" settings and the pulls I just had done on an actual DynoJet.

Car is a 2016 GT A6 with 3.15 gears
Mods:

JLT CAI
GT350 IM with 47# injectors and stock TB
Resonator Delete
Muffler Delete
E85 Tune from Shrader Performance

I still have factory exhaust manifolds/headers and factory Cats.

Weather was sunny and about 75 with 40% humidity.

SAE CF

Needless to say I am happy with the performance.

Those are very good numbers! I made 469 rwhp and 439 rwtq on my Bullitt which has the GT350 intake and tb, in addition to catted LT headers and an x-pipe with a Lund tune on E85. My hood was also down during the Dyno run. This was on a DynoJet Dyno.

Nice!! My next mod is likely headers.

Yessir! LTHs Will certainly put a huge smile on your face. Which headers are you considering?

Do you have the before graphs too?

The Mustang Dyno graph is before the intake manifold.

Wow, 482rwtq...did you LS swap that thing?

lol, no. It’s crazy. That’s why I went to a different place to have another Dyno verify the power.
