Hey guys, Saturday I'm takin the ol' TA to Famoso again but wanted to keep my "tuned" PCM in, because it's got the correction for my gearing/tire size. When I install my stock PCM to see if I get any gain over the "tuned", should it have been driven a while before hand, since it hasn't had power to it in over a month. I've never done this, just wanna run my best when I get there!
