Ok, here's a question for you geniuses out there: MTM says they get 368 ft/lbs of torque for 306hp. GIAC says they get 315-360 ft/lbs of torque for 300-315hp. That's a 14% range on the torque! MTM seems to know exactly how much torque they get, but GIAC can only guess? Personally, I'm all about torque, HP is just an imaginary number to me. I'm inclided to go with the 368 number because it's so exact rather than the vague number on the x chip...but is it really that exact? Has anybody actually pulled out an engine and measure what the crank REALLY puts out? Or put the chips in the same car and seen who runs a quarter mile faster? I'm looking for hard evidence on the torque from these chips, is it even out there?

Thanks in advance!

The GIAC twisted the motor out of my car. Does that count?

may indicate that the value is being provided over a powerband of interest.

But....there are dyno charts out there that you can look at....and 1/4 mile times. You just need to dig deeper.

HORSEPOWER IS A CALCULATED NUMBER.

TORQUE IS MEASURED.

Just giving one number for either is (really) USELESS.

You need to see the whole curve to tell what things are really like...

Hell, your car could make 600HP, but if 95% of the revs it's at 100HP, the car will suck :-)

I ran a best of 13.055 at 106mph with an MTM Gen II, scorpion, baileys and an S-Flo on 100 octane.

Very, very low 13's are possible with the MTM Gen II.

IMHO, they are totally different chips. The X chip pulls harder up above, the MTM pulls harder down below. For seat of the pants low end pull, I'd get the MTM. For all out high end pull, the GIAC X Chip.

For linear and fantastic pull, get the ABT chip, and for almost as much pull as the MTM Gen II and similair pull to the X chip, try the latest APR software.

These are my opinions from seat of the pants feel and drag strip runs. I've only run the APR and MTM Gen II at the track, so I can only speak in guestimates and seat of the pants on the others.

The torque is always = hp at 5252 correct?

Taner Halicioglu

4 * 5 / 10 = (4*5)/10 = 4 * (5/10)



But yes. Torque = HP @ 5252.. look at any graph

I was thinking addition...sorry

hehe no worries

and I do agree that the MTM pulls harder in the lower RPM's and the X-chip pulls harder above 4k RPM's. I now currently have kept the x-chip and sold the MTM. Bottom line the X-chip overall feels faster to me, sometimes scary fast! I think that the MTM chip is probably a safer bet, but I was tired of being safe. It's just a matter of personal preference.
