i want to know if im the only one with this problem. i thought i saw a video of another guy who had a wotbox and turbo and his car sounded like it was doing the same thing as mine. ever since installing the wotbox, i have a backfire in between shifts when i am hammering on it, its very consistant, pretty much does it with every shift when im at the track. ive checked for exhaust leaks,plugs,changed tune 3-4 times.car runs great but i cant take the popping anymore. i plan to bypass and remove the wotbox to see if that is in fact the culprite. i cant think of anything else that would cause this.i thought it was from hitting the rev limiter but that has been corrected. just curious about other guys using the wotbox, hopeing i can play with the setting and fix it...wanted to know if anyone else has figured it out.
