I have the Dyno Sheets form AMS

 

Nice numbers, I'll guess that its an Evo VIII?

 

Sucky. Should be over 300whp/wtq easily. Show us the graphs. I have the exact same mods minus the intake and have at least 300whp/wtq, though probably more. Drag times in sig with this setup...

 

ya i also thought something was off with those numbers...

 

I didn't even see everyone elses comments and had to go over your mods a few times cause something didn't add up. Were you running 87 oct or something? You need a second opinion.

 

what kinda fuel? that the big ?

 

and at what PSI?

 

03 turbo or 05 turbo which is bigger...and what boost level..

 

umm maybe its stock boost because i have 280whp with stock boost

 

If thats an 03 turbo and on 91 octane its acceptable. If not id check your plugs and start with simple tests, ie compression and boost leak to find out why your car is not running as efficiently as it should.

 

He has a Hallman so how would it be stock boost?

 

OK I was at work when i started this thread.
The psi is set at around 22, 93 octane gas and it's an 03 with 27K miles.
The guys at AMS told me that the car was running rich and the timing was set very high. They did some diagnostics and didn't tell me that anything was wrong with the car.
Al did the custome tune on it.

AMS told me that if it was little more lean it would have produced well over 300hp and still was very safe to drive.
The graph is attatched

 

they know what their talkin about and def. should be more than that! how do you like the aem intake?

 

I like that way it looks and sounds with the bov. It almost sounds like it has an externally venting velve. As far as HP gains I really can't tell.

 

The AFRs do look richer than normal, especially for a custom tune, but then again a custom road tune is more accurate for actual driving while a Dynojet tune is often not optimal and must be adjusted once you put the car on the road. This is why Mustang Dynos are so valuable, because they imitate road conditions, which makes a dyno tune work perfectly on the street.
