Re: Importance of a proper tune.

So I have done some more tuning to the van. Worked with the AE and timing as well as the PE AFR. I was also recently making some datalogs. I decided it was time to enable the speed limiter on it after this datalog. If it actually reached this speed, it might not have taken it long to get there, but we have NO interest in going this fast on a public road in the name of safety, even though it MIGHT have been 1:00 AM.
