ouch. its his opinion and we all learn from it. however, i COMPLETELY agree with jackandjanet from the start. justin is a stand up guy thats very good at what he does. he might not be right the first time EVERY time but will do whats necessary as a business man to fix the problem. especially when it's a n/a swap to blown, there will be a learning curve. i will need his advice on my future plans as i was very happy with the tune i got from him on another vehicle that was not an ordinary swap. imo

 

funny you ask that, i do have an intake that requires a tune (jlt) also i have a 80mm TB that he told me would not change anything....

all mods were mentioned when ordered, after first tune i had to emphasize that the intake requires a tune and insisted the tb would cause it to run lean but was told i was wrong

 

Ok here is the update... Justin was correct and it was a missfire on one of the coils on the PS bank. Truck finally runs and I will send another datalog to Justin so he can finetune it tomorrow. I do want to say thanks to Justin for working with me all the way through this process and I would and will recommend his tuning to everyone I know. Also thanks to everyone that helped in this thread!

Thanks Dave

 

glad you got it figured out...

 

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.
