Burger JB4 vs AFE Scorcher - Piggy Back Tuners

[L-GX550-P]

Oh yea, the difference is very noticeable. I've had a station here that had exactly e50 in their tanks for over a month. It's legal to sell as low as E50 as E85. That worked out great until I had a full tank of E85 that I had to keep diluting and stay out of boost.
