So I had my car taken to "Strictly Performance" tuning in Portage Michigan, right outside of Kalamazoo. First time the car has ever been dyno tuned. For the record, they also use a legit Mustang Dynamoter.

Mods are as follows:

3.23 gears (came with 2.73 stock)
built 4l60e stage 2 racing transmission
3400 TCI Stall
Transmission Cooler
Poly motor and trans mounts
Aluminum drive shaft
Ported and Polished Throttle body
243 heads (from a 2003 Z06, not ported)
BTR Stage III Cam
Speed Engineering 1 3/4 inch Longtubes
Texas Speed Catback with built-in cutout (it's their newest one, listed here:https://www.texas-speed.com/p-5187-t...d-cut-out.aspx ) For the record, I was not able to witness my car being tuned, had a buddy drive it up there so I do not know if the cutout was opened or closed.
Off road Y-pipe, 3 inch
SLP Lid
Ported LS6 oil pump
LS2 timing chain
160* T-stat


Pretty sure I missed a few things here or there, but that's the meat and potatoes of the build. So I knew that it being a Mustang Dyno, was likely going to read low, but the numbers came back as 352 WHP and 415 WTQ.

OVER FOUR HUNDRED TORQUE? That seems very unusual to me. I will try to upload a picture of the graph, it's a steady climb for the HP except for one hiccup at around 3,900 RPM. Climbs more steadily past 4,500 and peaks at around 5,950 if I'm reading this correctly.

I've read Mustang Dynos routinely report 15% lower than most dynojets, so figuring that I could be at over 400WHP with a dynojet, but how do you explain the torque? The graph legitimately says 415 TQ.

sounds about right. unlocked converter torque spike, unlocked low peak hp #s, coupled with bad headers and worse catback and you get 350hp from a heads/cam car.

When you go pick it up head over to US 131 for a few passes. That will quickly confirm things

OP, That cam should peak way more RPM's than that?! Also what intake are you running??

What's wrong with the headers?

They're barely 1.7" id chinese specials? The new ones are better then the old ones (which are actually 1 5/8) but still aren't even a true 1 3/4 header.

Give up power to a bigger tubed header.

Okay guys, I have it figured out, I think...

A 2017 Camaro SS 1LE went in and dyno'd on the car, bone stock and made 360RWHP. They're rated at 455 crank, so based off of that I ought to be pushing 435-445HP to the crank.

The torque numbers are false readings, I was told the converter flashed, my actual torque number can't really be deciphered, but it's probably around 390RWTQ+

I've been driving the car for about 3 days now, it's ridiculously fast. Haven't raced anyone yet, don't think I will on the streets. This car draws too much attention. With the converter I'm always in the powerband, so the car can accelerate quickly from any speed and any gear. Plan on taking it to the track in late summer or early fall. Hoping for low 12's, I'll be on street tires.

Ah see now this makes more sense lol. A 2017 SS is more like 400 rwhp on your average dyno so you are right in that similar range

I have the stock LS6 intake.
