QUESTIONS & ANSWERS
Ask a Question-
I have a Raceme Ultra, will that work for your custom tunes that are MM3 style? if so I have 2021 with Aisin trans, which single tune would be recommended for daily driving that works well with the Aisin? Thanks
Yes, you can use the tunes with a RaceMe Ultra. Normally if you are going to run just a single tune, we would recommend a 25 or 45HP tune if you are towing a lot. Otherwise, you can run a 75 or 90HP if you are just daily driving the truck empty. The tuning will help work with the Aisin trans to shift as nicely as it can.
