Naturally Aspirated Holley Base File

If you are looking for a base file to tune your own vehicle using Holley EFI or Holley Terminator X 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 a Terminator, Terminator X, HP, or Dominator ECM.

All base files are essentially an "Almost Complete" tune. The Setup, 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 .
