Hey guys, I'm new here and just have a question. I have a 13 Buick Verano turbo that was tuned by BNR and I have lately had an issue with it stumbling/ hesitating at or near WOT. I logged some data on this yesterday and noticed my TPS percentage fluctuating from steady at 84.7% down to 72% when I know I was at WOT. Is this normal, or is my tps going bad. I know the 84 is normal, but shouldn't it be staying there until I lift? I've noticed extremely high idle occasionally as well during cold start. Like 2000 to 2500.
