While I do think much of this stuff is very informative, I somewhat agree with the OP. Tune, then post before and after results.
Jerod, if you get any useful tidbits from Clark, can you please share them with the community? We'd all appreciate it.
I haven't tried it yet due to all the back and forth talk about whether or not it's worth it to go to SD and I am still a little confused on how the SD curve should look. Should it mimic your curve Jerod or should we start off with what WRXSTI-I suggested in the RR forum?
"pretty good base SD table going by using a single value for each column from where 0psi is for your location (mine is 14.7abs) and go from there."
Clark, where did you start off on this?
