Little pissed off just spent a shit load of money for 20 hp! I got the 12lb pulley, 2mm head gasket, aem ems, 750 injectors, did everything right to my knowledge. I know mustang dynos give lower numbers then a dynojet but to me it was just a waste of money if i can't get the numbers up to at least 350 whp.

I'd post the dyno sheet but don't know how.

What do you guys think I should be seeing? Could it be the tuner it is his first aem? he had it for like 3 weeks now!

 

I would be pissed off too. You can pretty much get those #'s with a stock pulley.

on my vortech i made around 355 at around 12psi

My car was dynoed on a dynapack though.

 

my car with a comptech pulley is puting out close to those numbers i think it could be the tuner especially if he hasnt done one before. my opinion you should see close to 350 with those mods and a good tune.

 

Keep in mind that EVERY car and EVERY dyno are not created equally. Altitude, weather, and many other factors have a large effect on the numbers that are printed on your dyno sheet.

Yeah I'm going to take it somewhere else when hes done with it. The guy is scared to take it to 9000 hes only taking it to 8300 and the boost is at 10.06, I don't see it going to 12lbs at 9000. The air fuel is staying between 12.4 and 13. How lean can you go and still be safe?

 

Am just curious as to where you got it tuned i see your from PA
I was thinking about taking it to Jeff Evans tuning, i heard hes REALLY good.
Hes in PA.
Thats not where you took it right?

 

my numbers are in my sig, and i'm running a little under 10 psi (3.3" pulley). not sure how much differences in dyno it is between our tuners, but seems low

 

my car made 348 on a dynapack with just 7.5 psi....

 

Well, not taking it all the way to what the redline is suppose to be will kind of hurt things a lot.
