Tuning box performance
The two that seem easy to find are VR tuning and Racechip boxes. They both say they increase hp and tq by around 40-50. Not sure how accurate that is.
looking to pick one of these up after some proper maintenance to my car.
I’m not looking to compare both options, I’m looking to see if anyone can recommend a company that does tuning boxes.
I can see you’re flat out against tuning boxes
