Dealer can not reprogram for a tune. They won’t dive into issues you’re having from modifying their product. Nothing good will come from involving the dealer unless your resort back to stock and advise of issue
OP Followup, seems have been just the gas, have filled up with just 93 twice now. Running in map2 and have no issues at WOT. After another refill I will try the blend again and will see how map3 performs.
For the most part I think it would apply to any performance after market downpipes. I could explain the science behind it but im pretty beat it’s been a LOONG day on top of a LOONNNG WEEK. Maybe tomorrow or Monday.
