i love my 37s never stock again and mine didnt even like the stock tune any moreyup! still on 37s. i wouldnt reset taps, ill leave it as is and let it learn as i slowly increase throttle increments. it may be different now with the defuel set right but i tried putting stock tires on my rig few years back for the track and it flaired, bucked and straight up gave me the finger the whole way down the track compared to the 37s.
