Comparison of Evolve/7030H2O/progressive JBD with post #60 data with JBD fixed at 0%. The progressive JBD mod data looked good so the top end was increased. This run was with the top end set to ~90% on the total JBD capability. Also, this new data was on a heat soaked vehicle with multiple full fuel runs on it in ~91F humid ambient conditions. The owner wasn't being very cautious with low rpm full applications for the new runs to test the low rpm torque curve characteristics.
The mod definitely helps extend the top end torque/hp and gives more area under the curve. Also helps minimizes peak low rpm torque for non-careful applications of fuel (see post #27 for example where normal peak torque for 3rd gear pulls occurred ~2100 rpm ).
