I was thinking about this and wondering if you guys don't think it might not be UpRev's problem, but rather the effect of a Nissan safety feature responding to what it perceives as a problem. What I mean is that maybe Nissan has built in coldstart safety features. I know I've felt that hesitation where you push down and it does nothing and then lurches forward. I know the feeling you guys are talking about because I've definitely felt it (to a lesser extent) on my stock tune. So maybe its the ECU responding more aggressively to protect the engine during cold startups. I know there are lots of "maybes" here, but I'm just throwing out a somewhat logical explanation that may give someone an idea as to what's going on.

Just being logical eliminates tuners from the equation. The only two things everyone has in common are the uprev ROMs and the Nissan ECU. I doubt, after all these years of programming for Nissan and uprev's usage of other stock ECU functions, that they would have mistakenly cause a silly issue like this. Kinda leads me to think that the culprit is the new player in the mix...
