JMS Chip - their tune on a '15GT

[Todd15Fastback]

I did a search and could not find anything related to a JMS tuned '15 GT.

Great numbers from a tune only, that's for sure.

That's not tune only. They had a frpp cat back on it.

My livernois tune was ACTUALLY tune only and was 22hp

Correct but......we have seen gains of 1.6-3RWHP only from cat backs. Or are you saying that the FRPP is different than SW or Magnaflow?

I got 5hp from gibson on the Dyno. Flow form claimed 20 from gibson.

Even if it's 1hp from the exhaust. It's NOT tune only. I posted a graph and video of actual "tune only"

What else can be added to a "tune only" and you still consider it tune only? Intake? Headers?

Not tune only and a cat back.

Good numbers for tune and catback.

Too bad they didn't do a tune only, then tune and cat back like I did. There's a difference.

Mine made 426, tune, cat back and jlt. They are basicly the same. 424

Welp....JMS just posted this on social media. This is a different car than the video I posted in this original thread.

If this is true, that is some serious HP/TQ increase from just a tune. WOZERS...

Something is off. Their base HP is low too. Most are clocking in at 385-390 stock. No tune is going to get you an over 10% HP gain.

All dynos are different. Number don't matter. Gain does as long as dynos is same and all correction factors are left the same.

Yeh but again a tune isnt getting you 43hp no matter what you do. Something is off with their tests. Tune AND catback will get you 25hp or so, def not 40-45 on a stock car with a tune.

It's just more manipulated graph advertising like Magnaflow and the catback systems were/are doing claiming 20-30hp from a catback, where no one has seen more than 5hp across the brands.

I agree as well. Very, very skeptical of the numbers. I posted on their FB post asking questions about this. Curious if they will respond.

 

[Blk2015GT]

VERY skeptical. People are making these types of gains with a tune, CAI, catback AND headers- full setups. But somehow this tuner can make 43hp just with a tune on a stock setup?

Unless this tuner I've never even heard of has some formula the big names (Bama, Lund, Diablo, etc) who have been around a long long time don't; which I highly highly doubt.

Of course you are......

Of course you are......

Yeah, of course. You're a real freaking pleasure. I bet you're the life of the party.

If I could only be as smart as you. I can only hope to reach that intellect level some day.

I've been in the car game for a long long time, and anyone who takes a manufacturers claimed HP gain as a fact, is a fool.
