It worked but not what I expected. It brought out better launch but there are still some restriction that I can't pinpoint. I haven't tried burning out but I have took it to the tracks and it made a difference in the traction not kicking in when you didn't want it to. My time was 14.588 1/4 vs before it was low 15s on hot summer days with traction kicking in during launch and slowed my times down. I'm expecting better times in the winter. The light keeps illuminating but it take less the 5 mins to put back to original. Thanks for all your help.
