It's very hot here in Arizona and well over 100. Today for the first time in a while the car was up on a Mustang Dyno -

471rhwp first pull...?????It still needs to be be fully tuned as this was the start of the tuning but I was expecting much more?

Question - How much hp difference can quality tuners make? Meaning two well known tuners going head to head - could the difference be 50hp-100hp difference?

What is the average increase on a Dynojet -

I've been on both and others but is there a formula increase on the Dynojet or just knowing it's more kind of thing.

Also - Is there a formula for loss in hp due to weather temps etc...

My goal is 530 - 550 rwhp with my current mods - Am I way off?

Thanks,
Chef

If your air/fuel is around 12.7-12.9 and your timing is around 25-27 degrees, there is not much else you can do to make 50-100 HP more, maybe 5-10.

Mustang dynos are about 15% less than a Dynojet....

copy that...

+1; and that number would be even less if the two tuners used the same dyno with the same weather conditions close to the same day.

Making power is the easy part as it's just timing and fuel. Making it drive nicely, etc is the hard part. A mustang dyno reads anywhere from 10-15% lower than a dynojet.

Haha but you'd never know that reading the dyno section.... every setup that doesn't make ungodly numbers and it's "probably a bad tuner or tune" ...

Well, duh, absolutely. Don't you realize that the real world is just a very long dyno without the tie downs?
