4530 Depends on what your goals are. Also depends on if your mods have changed or are going to change since you've had your protune. Every tuner has a different tuning style. Kinda like a bomb makers signature we are all different. I've been pro tuning for years and years now. Both George and I pride ourselves on our drivability of our tunes. Most people end up with what we call a sledgehammer tune which is where most tuners will take a global map and tailor that to the individual car, I start from scratch and fine tune everything specific to each vehicle. No one of my tunes will will every be the same. A map for your car will be completely different from a map from another car. No copy and paste stuff from me
