So, been tuning this truck SD mode for awhile now, when in boost, it feels sluggish, and is not as fast as I think it should be.. I feel like its on par with a stock truck.. I put a MAF back on thinking that would help.. Still does the same thing in maf mode.. Heres current log and tune for maf only.. Yes I know fueling still tunes cleaned up..
