I have had Justin tune two trucks for me. I am very pleased with the customer service and quality of his tunes. He is a very patient person and stand up guy that really knows his stuff when it comes to tuning these trucks.

X2 he wont stop until tune is on point. still to this day working on fixing a few bugs with mine after cam swap.

My truck was a PIA to tune....always had idle surge and what not and took too long for him to get back to me at times. Yess I know i am not his only customer....Everyone wants a tune so I finally gave up and bought EFI Pro.

Yeah,same here. I assume he has a ton of emails to answer.
