so finally got my car tuned and I'm pretty disappointed with low numbers, not too sure of what to think of it. After the tune the AFR(11.9-12.2) was good and my IAT's were low. I feel like something is wrong and not sure where to look, but I'm almost to the point of just turning the car back to stock and just selling everything. Anyways heres my mod list and graph, I know people with similar mods are well over 600. Granted my tune was done on a mustang dyno, it would still only be around 550 on a dyno jet which still seems low.

3.85 pulley holding 8psi
CA test pipes
borla mid and x pipe
flowmaster outlaws

I would expect more like 550 on a mustang.

Do you know how much timing you are seeing?

[11bravoss]

If I remember correctly it was around 13 or 14

100% Meth?

Should be more. Looks like a poor tune. You should make some Datalogs and have them reviewed by an expert.

im making 565rwhp on a loaded mustang dyno .. i have a D-1 procharger and headers only, if i add meth i should see 600-620rwhp.

Meth was 50/50. I'll have to see if I can datalog with my SCT

Did you get a baseline on this same dyno?

Remember it is just a tool. If you don't have a baseline you really don't have a comparison. That being said, that seems low. How does the car drive?

[SSDan]

I know we are likely to throw out thoughts on things you already know so with that in mind - what gear was this pull done in? Was it 4th gear if a M6 or 6th gear if a A8? Those are the gears that give 1-1 ratios and thus the best for talking about and comparing dyno numbers.

Definitely looks low. As stated the dyno is just a tool. Is that the corrected number?

[Atomic Ed]

I know several of you are reminding us all that a dyno is just a comparison tool, but IMHO, this low of a number is just too much to discount as dyno variance. Yes a 50 rwhp difference is easily seen between dynos, but 11bravoss is somewhere around 75-150 rwhp short....that's either something on the build, or a dyno really out of whack.

Here are the PIDS I think you should data log on a full pull:

1. Timing advance (cylinder 1)
2. Command (Air Fuel) Ratio
3. Short Term Knock Retard
4. Intake Air Temperature
5. Manifold air pressure
6. Barometric Pressure OBDII
7. Engine RPM

I'm sure the Procharger guy will chime in also. At least contact them.

You need to baseline your car before any mods so that you can measure the increase after the mods as well as have other data for comparison.

What does the individual who tuned it, have to say about the results?

[11bravoss]

they never did a baseline because they immediately installed the Baro breakout kit and and threw off the MAF so they had to do a base tune just to roll the car onto the rollers. The car has even power through out the pulls, but the odd thing is before the tune tires would easily break lose from the can tune from procharger with the stock 3.9 pulley and no meth, now in first I can hit and the tires don't even really break lose. not sure if its just because of the more even powerband or loss of power from the tune. Car is a M6 and all the pulls were done in 4th.

do you know if I can datalog these with my sct x4?

he didn't really say much and kept saying its because of his dyno, but my ass dyno wasn't impressed either
