Do these numbers sounds right?

[1KleenSVT]

I just had my car dyno/tuned on tuesday and my end numbers were, 392HP and 412 FT Lbs TQ. I bought the car with some decent mods but i was expecting better. Mods are in my sig. It was also on a Mustang Dyno BTW.

From what i understand Mustang Dynos are usually about 15% less than a regular dynojet, but even still your numbers seem low.:shrug:

Go to another tuner...sheesh!

 

[Mystic03]

with that combo you should be well into the 500rwhp/tq range...get another tuner

 

[03SVTKB]

Oh dear! Those are very low. Yeah try a different tuner.

OP
Your numbers are low.
Did you buy the unit used or direct from us?
Here is a few other questions.

numbers way low for those mods, even for a properly calibrated mustang dyno

yes, but what sucks is that it could be an improperly calibrated as well.


I would check it on a dynojet. If it's 480+ rwhp, it SHOULD be fine. But looks like it either needs a seriously better tune, or the motor is hurt.

Your numbers are low, I made 470 on a Mustang Dyno w/2.76, tune, ported TB and Plenum.

ya, but mustang dyno's can be all over the place with their numbers, so they are not really comparable on the net to others. But when used correctly tho, they are the better tuning tool.

 

[twhitey]

those are the lowest I remember seeing for a ported eaton

 

[i8urSS]

those sound low for a stock pulley. i would def head to another tuner. hope it works out for you buddy

Agreed, when comparing numbers Dynojet should always be used as they will be more constant. There's no telling what happened with this as it could be the dyno, the tune, or the motor. If you could post the graph with the run conditions and AFR along with a datalog if possible.

Well im not really concerned with the motor because it only has 3500 miles on it, hopefully it is the dyno itself. Im going to find a Dynojet dyno sometime and check the numbers.
