Forced Induction Gen 4 Base File

If you are looking for a base file to tune your own vehicle using your own HPtuners software then you are looking at the right place. All purchases are subject to approval. Not all engine combinations are supported.

This is the correct option if using an E40, E38, or E67 ECMs. 

All base files are essentially an "Almost Complete" tune. The MAF Curve, VE table, Timing Tables, etc. will all be extremely close to what your vehicle is going to want. However, YOU are the one responsible to finish the tuning process . You will also be supplied with the correct HPtuners channels to datalog if on stock ECM.
