With the dfco, can I set the upper and lower Params to say 9600-9400rpm so it doesn't work.

I guess it depends how much control you want over the fuelling, for me running the boost level I am it flies through the 100-200kpa range pretty quickly so having half the resolution in there is not a big deal and realistically people used to use fudged $5D tunes to make a boost map from the 20-100kpa ve table, and they worked ok, so we're still talking twice the resolution in the boost table if not more ....

my brothers Turbo V6 is running a 3 bar map and at the moment 12psi, its still plenty tunable to get fuel right on boost so I reckon its all good, having said that, a true streeter would be the test for how drivable and tunable it would be on a daily basis!

My speedo is out and it's also set for manual transmission but I'm running the th400. Will this be effecting the logs?
