Defiant Autospeed tuning review.Quick initial review on my Defiant Autospeed (Dave) Tune. Got there at about 0900 Dave decided that it would be better to start off with a stage 2 base tune. The stage 2 Map ended up being pretty far off. A/f through out the range was in the 9’s and ten’s so with the Fuel map just about everything was zeroed out and started over. To make a long story short after a lot of road tuning leaving Dave's house at about 1600. The car feels like a completely different car now. So much more power with smoother total response. It just shows me how bad my old tune really was.If you have a UTEC and are not running Speed density, you need to be. If you are unsure of your tune, you need to go see Dave. I learned so much just be watching him tune. When Dave sends my last data log I will post it up for you to see the final results. There is still a little tweaking to do but it is 95% of the way there.
