    Default Dyno'd the Black Pearl Today. She Needs a Doctor

    Had the Black Pearl dyno'd today on a Dynocom 5000 2wd chassis dyno (Mustang clone I'm told). Attached below is the readout. The a/f is super pig rich. .7/.8 Lambda, 10.3/11.7 stoich. That explains why I'm getting what I think is bad city/frwy mileage for the motor combo. I'm not going to start a flame war on the tuner. He has a good reputation and many here have used his tunes. It's clearly a safe tune. I will email him for an update. However, I'm certain a ton of power is being left on the table. The O2 sensor was placed just before the cat in a bung I had installed some time ago. Motor mods are as follows:

    Stock 5.9 short block, 210x cam with 1.7 rockers netting .540 lift. M1 with 55mm F&B throttle body, massaged oem heads, headers, MSD ignition, electric radiator fans, MSaine 2800 TC, TransGo kit, 4:56 gears on a Detroit locker.

    I was looking for near 300 rwhp to the wheels. So, will getting the a/f corrected get me near that 300 rwhp mark? Also, In your opinions, what kind of power should I be making with this motor combo?

    Your thoughts, opinions, suggestions, flames, bashing's and insults are encouraged and welcomed. Thanks in advance.

    I know every dyno is different but most stock trucks put down about 200 to the wheels. Your numbers seem very low. Are you at high altitude? I'm assuming those are unadjusted numbers

    Not stock. See mods. Altitude was approx 2500 ft. Not sure what you mean by "adjusted". Those are rwhp results.

    That's my point. You're not stock and you didn't even make what a stock truck makes.

    By adjusted I was referring to correction factor (for altitude and weather).

    Holy shit. Give me a call when you're ready for a proper tune. You're 75 whp or more off. Fueling is not going to fix that, I assure you.

    I would guess you're at least 50hp down. Something is happening besides A/F

    Thanks Ryan. The dyno guy will get me the session info in a couple of days. I want to see the timing, map and tps readouts.

    I'm certain timing is the problem too.

    If you've never had any updates to the tune based on dyno or data logging previously then inwoukd give your current tuner a chance before jumping ship.

    Its also a mustang dyno is going to read lower than a dynojet. And you won't get anywhere close to 300ho with current mods. As Ryan said, 50-70 more max and that's on a dynojet.

    I had less MODs and made 300whp 2 years ago. Granted I was only 200' above sea level VS 2500'.

    IMO, Dynos are a tuning aid only.
    Comparing Dyno numbers is 100% worthless unless it's the same dyno on the same hour of the same day.

    This is the second tune. I'm getting the session data from the shop so I can see all the parameters. I'm sure timing is an issue as well.

    That's true. But have always wanted to know the power output. Many with the same combo say 300 ish hp is common. BTW, air temp outside was 45 degrees and altitude was 2030 ft. Didn't get any DA numbers.

    Heads make a huge difference. And his cam is a baby cam.
