Whats the difference in tunes?

[Power Hungry]

Once again, Jack is on the case!

There is much more to custom tuning we provide than just twiddling the "custom options" that come on the programmer. Those options are there to allow customers to make some "fine tune" adjustments based on parameters that are often subjective as specific to a persons tastes. This is especially true with shifting characteristics.

Tuning for a CAI or exhaust is done generally to eliminate the resultant lean conditions these modifications often introduce. In many cases the lean conditions are manageable by the ECM, in some cases they are not. It depends on the specific components, ambient conditions, fuel quality, and other factors.

Given the modifications you indicated, custom tunes are surely the way to go... even if it's just 1 or 2 programs. Most often, people will find a good program that fits their needs and just stick with that. Others, like enthusiasts, may switch from program to program as the situation demands. It all depends on what you're looking to achieve.

I hope this is helpful.
