    When I upgraded to the ET low boost wheel. I was warned that I may get some hesitation if taking off at certain rpm with the JD intercooler. At first I did not notice a thing. But as time went on after a short time of cruising and then i pinned it, it would hesitate. Or after doing some tow ins. Never really worried. I did by a AFR meter but have not tried it yet. Which reflash do you have?

    Phil is on to it. Once your clutch goes say good bye to your plugs.

    Dont forget to check and recheck ALL of your hose clamps. there are some exhaust clamps you cant see in the far back. Also the intake lines and intercooler hoses as well. If you havnt replaced them with stainless rust free pieces, you might find that synching down old rusty clamps tend fail shortly after.

    Check your air filter as well. If you still use the air box, get the r&d reusable filter so you can just wash it and put it back in. I clean my air filters every other month.

    syk03t,

    What speeds are you hitting with the Reflashed ECU & LB Wheel?? Also what pitch and RPM's? I have a 13 FX and am trying to find #'s for a mild setup..

    Thanks
