Good to know. I just went back and reread the whole thread on the 95mm tb and msd from about a year ago, I guess unported the 95mm tb and msd are fine on stock tune but seems the ported 95mm tb requires a tune.

You need to talk to the porter, cutting away the transition ridge can cause issues. I did not have an issue at all with the 103mm. low speed high gear and with no cats there is some sort of bad harmonics, never figured it out, but that was with many different tunes. Putting cats in fixed the harmonics.

Going down the path of what can I get with no programming is a path of disappointment.
