I'm extremely happy with the results from your tuning. I never thought I could get high 12's low 13's out of a old 99-02 whipple. Excellent to work with and a great guy to talk to. I recommend your autocal program to anyone and everyone.

 

I just ordered myself an autocal about a week ago, the anticipation is killing me lol I'm not FI yet but it's definitely in the plans

 

You ll be happy with the results. Just know that it goes take him a little time to respond, but he's a really busy guy.

 

my head against the wall going with another tuner (sponsor)
i shouldve waited and went with justin to do the autocal

 

looks like blackbear and two sponsors on ls1 tech are reputable to tune
i am selling parts as we speak
gotta get bigger injectors for my set up before i give justin the call

 

Justin know his stuff for sure!

 

Wheatley, Nelson and zippy are also great tuners from what I hear. Zippy actually helped me select a cam and stall so he's a good and knowledgable guy to talk to. I just liked the autocal program because he could actually see what my truck was doing and adjust accordingly.

 

Justin is a great tuner on these trucks! He even surprised himself last time he tuned my truck. He asked if I had long tubes, I said no... He says, Well it pulls like it has them.


Needless to say no one else will tune my vehicles but him
