Noticed when i went to the track last weekend that when on my 2 step the tps signal stopped at ~46% and as soon as i released the 2 step the car went 100% in th scanner. Only changes i made were to the tune was to change from e85 stoich back to regualar gas stoich, i upgraded to a bigger throttle body but retained the origonal tps sensor, moved my odb port, wired my wideband in to my ac pressure port, and i adjusted what rpm my water meth kicks on. I checked my last logs that i had and its never done this. Any one got any ideas?
