[Circuit]

It's been 2 months and I still love this little black box. Three weeks ago (just after they were back from vacation) I got my custom tunes. I have been driving on my custom 93 octane tune with 94 in it leaving it on Bill's settings. Compared to the canned tune it is very much worth the $30. It is exactly what I was looking for. The truck drives smooth and fast. Downshifting is the way it should be from the factory. I can get 20+ mpg if I stay near the posted speed limits.

I am curious, since the tune is labled "93" performance should I kick the timing up 0.5 for the 94 octane? I tried it at +0.5 and +1.0 and it didn't really seem very different. With the canned 93 perf tune when I upped the timing +0.5 there was a noticable difference in power.

Just trying to have my truck be the best it can be. I am very happy with the way it is now.
