I did tune for your intake, as I developed a file for the JLT intake after tuning several local ones on the dyno. For some reason your truck was not like every other, that happens sometimes.
TB's don't make mass air vehicle's lean.
Be careful how you lay out the facts, I'm well aware a JLT needs a tune, but a TB does not change fueling on a mass air based vehicle....maybe if you had an old speed density 92 bronco, but not on a 97+ F150.
