The Big 3 on one truck/Dyno

Notneb · Jun 25, 2016

So as a few of you know I've been trying to get all three tunes on one dyno, and today Mike *No Limit Fab* and Cory *Diesels & More* came through and managed to get me a GH/AS Tune to compare against Sp@rtan and P!P.

We did 2 pulls on each tune, giving the truck time to cool down, swap to stock, then to then next tuner. We then took the best of each and laid them together for a side by side comparison.
GH/AS is Red, P!P is Blue, and Sp@rtan is Green

And here's just how loud my tires are compared to my exhaust... Really re-thinking some Toyo RT's now... Lol, anyone want to swap for some SS M16's?!

Mods for those who can't see my sig: No Limit D3letes, No Limit Stage 2 Intake, Midwest SS IC piping kit, H&S Fuel Filter/CCV Mod *reroute to downpipe*, 5" Flo Pro. Tires are actually 34" in diameter.

Nice, pretty impressive #'s

Wow. Surprised to see GH/AS so far to the right. Is that theoretically...or realistically hard on the rods to be making a fair bit more torque lower in the RPM range? That has to make for a fun driving rig, as long as it's not too hard on the motor.

Thanks for doing this. Looks like they all have their good points and it depends on what you want to do with your truck.

The variations you see there are due to the variances in RPM starting point of the run. You can reference the beginning of each line. I'll elaborate more on this when I'm in front of my computer.

Drag the lines until the starting points are on top of eachother for a better representation of how they actually stack up. If that makes sense?

Ok. Between you & Matt, I got it...mostly me not being well versed in dynographology. Lol.

I guess I was thinking same truck, same dyno, same operator, should lead to comparable results without "adjustments". Again, see above...lol

Thanks for the replies.

Again, huge shout out to Mike @ No Limit, he drove in to work today just to get a AS/GH tune for an apples to apples to apples comparison! He never fails to amaze me on the quality of his customer support!

Very cool! I love the horsepower to torque ratio, better than 1:2!

jcain · Jun 25, 2016

Which tuning level and revision from each tuner ?

Notneb · Jun 25, 2016

SCTx4 7015: P!P v8 LV 4
SCTx4 7015: AS/GH Race *newest version*
nGauge: Sp@rtan Warhammer Beta

Couple questions:

1. Have these numbers been adjusted or are these numbers representative of true at the wheels power?

2. What kind of risk do these power numbers pose to stock rods?

Notneb · Jun 25, 2016

Adjusted, if anything it's reading on the low side. Rods aren't an issue, boost is held pretty low until around 1800rpms.

For clarification all # are sae corrected

Notneb · Jun 25, 2016

^^^ that's what I meant

Their dyno is spot on as well. Track times put my truck at 615, dynoed at 614 on their dyno. Glad you guys finally got to do this!

Jomax · Jun 25, 2016

Ran my truck today as well. After I got my numbers we decided to get Tony to somehow get ******** to see on his truck.

My truck has S&B intake, ****** pipe, MBRP rear duals gear head race
