So I got the revision for my SPD tune over a week ago (thanks, Charlie) I opted to extended the shift points, lock out OD and try the open vane at idle option. I had some computer issues, that is why it took me so long to load it (suck it windows 10!). But got it straight and loaded the tune last night and took it out for a cruise today to help the trans relearn. What a cool tune! At idle, the truck sounds great, I previously added two Dynomax Bullet mufflers to calm down the whistle. Now, it is just plain gone at idle. Which makes me feel better about leaving early in the morning around the neighbors. I was informed that their might be a very slight amount of lag with that option, I didn't notice anything. It shifted very nice as well and not too aggressive driving through town. I only hit the highway for a one mile stretch, but man, was it nice not locking into OD on the on ramp before I merged on the interstate. Power wise, I am not sure, I am sure it is about the same as my old SPD tune, I know what to expect. I did not get on it because I want to let the trans relearn. I will get more highway time tomorrow on my commute to work.
