Should be interesting to see what you find out with that dyno.

derek - your sig shows the "eurocharged tune"....since your car made 433 rwhp stock, what did it make with the tune?

I just got mine tuned and i either lost power or my engine didn't have that kind of power in the first place.. I'm at 410whp now.. The shop is going to take a look at it again next week.

Also interested in the difference between p31 and the aftermarket tune.

It would be near pointless to have an aftermarket ecu tune on a P31 car unless it is paired with long tube headers. The P31's are simply not de-tuned and consistently make 500+ crank HP which has been documented on numerous occasions. Consider it a factory warrantied "tune" just as all the M157 models have as an available option.

Nice numbers derek! And on a Mustang! What was the temp like over there when you did the runs? And as far as we know, P31s are making 500+bhp in most temps.

khmergod

One question, 433 pure mustang, or dynojet correction?

I have a tune on a P31. Pulley and Evo 1 tune. Now at 451whp.

I don't know, haven't had a dyno done since the tune, but I'm bringing it in today to get some SS Brake Lines put in, I will see if they can run it.

Autoscope is air-conditioned, it was (jeez, I don't really remember) 70 or so in the dyno room.

Were you ever able to dyno it after the tune, id love to see the numbers.
Thanks

Pickles

I have a P31 engined car, & would love to see "documented" evidence that my car has 500+ HP.....so if you could show me, I'd be grateful.
NOT "HAVING A GO" here, I'd just really like to be able to tell people, & show the proof, that my car's got 500HP...I mean, it's a bloody impressive number!
Cheers, Pickles.
