Stratified S-OTS+ vs. Hypertech Flash Tune Review

I would like to see that, too. I am running with a few more flow mods, a 3" catless dp/rp and true CAI, pump internals, and HT works well with the increased flow within the limits of the stock K04 on pump gas. I don't know if I'm leaving much on the table on the top end. But the nature of the HT tuning strategy makes it softer on the low end. FWD limits usable power there anyway. Very sticky street tires break freely in 1st and 2nd now at WOT, so more low torque would not be beneficial. Coming in a few hundred rpm earlier earlier might.

I've never seen apples vs apples hard performance data between the two tunes at my mod level and would really like to. I don't intend to go big turbo or run higher ethanol percentage and am unsure that there is enough benefit to change tunes. If anyone can squeeze the max out of the K04 on pump gas, Lex is the one.
