    Please comment on my Plugs

    Spark Plugs: Motorcraft AGFS12FM1 (colder then the late model 22's OEM)
    Milage: 800

    Tune: Predator 91 Octane Canned (adjusted) Tune

    Does the Strap LOOK like it is halfway or closer to the Tip? Coloration of the strap. I know the ring shows it being too rich, which my A/F verified it as well. (10.5 after 5500rpms)...cant get the predator to go leaner at the top end without messing up the tip in and bottom portion of the A/F

    They don't look bad. I have the SCT Pro Racers package and a base tune from RWTD. It is nice to be able to tune yourself. I run the same plugs in my car with no issues. There was no evidence of rich or lean conditions when I checked the plugs during the Whipple install. I had some tip in detonation problems when I first did a pulley on the car. It was corrected by pulling a little timing a various load levels below 2500 RPMS.

    Please advise where you see that on the picture?

    The plugs only have 800 miles on it and I could never get a real story until it has a few thousand miles on it. The 22's I pulled out has the ring completely black which should be an indication of being to rich for optimum HP vs TQ.

    Also, the A/F Gauge doesnt show me any lean conditions but just at the bottom end...12.0 ~ 12.5, which is nothing IMHO.

    Is it difficult to use? Id my "X" tuner use it & it looked fairly simple.

    Predator CANNED Tune works ok. Im off a good 2 ~ 4mph from an actual tune vehicle...my 17* aint shit....LOL

    They don't look bad. The car should take a few seconds to transition when you go into WOT. So if you see 12.0-12.5 initially no big deal it is normal. If I go WOT at 2000 RPM it takes about 2 seconds to get to 11.8 and stays there to the redline.

    Hum...yeah, mine car jumps pretty fast to the 11.

    I believe the strap is telling me the that heat range is bit too cold, but im not 100%.

    It is not too hard to learn. RWTD has a support forum and so does SCT.
    It is great to be able to do things yourself. With the package the xcal2 links to your laptop for data-logging. Just do a 3rd gear pull form 2000 to the red-line then analyze the log and make any adjustments you need to the MAF transfer curve etc. U1arunit on this forum is also a pro racers package user.

    At least 1 range colder is recommended for any cobra with a pulley.
