MyDream and I did this yesterday to our Machs and we both agree on the SOTP Dyno, that you can feel the difference big time. We both have the feeling our cars get up an go alot Sooner and faster. Hanging problem fixed. His had the 9/32 hole mine was a tad smaller. Cost was about .02 cents for electricity- we got the flashing for free.
Anyone else feel the SOTP difference?
