As many know I have had some tranny shifting issues with stall. Well many on modularford knwos as well. I have had some the biggest names looking tuning my car. And with some mix up we think they said I needed to change strategy's. Well HPXmotorsports got ahold of me as they are Vendor on Modularfords. Chris Holmes. He asked to look at file and see if he could help. And help he has. He has already fixed soem issues and working on dialing shifts in now with me datalogging and sending him them. Great GUY and Great shop. They do all tuning for bolt ons/SC/Nitrous etc. I would recommend them t o anyone after this. Can't say more. I have found a new shop/Tuner that is for sure.
