Did you check your coolant level?HELP why is my over rev red light on all the time and cooling fan run on cold start up
who did the tune on it? Did this start immediately after it was tuned?May be something with dyno tune
BLP does a bench tune from what I know. So not via a handheld device. But I could be wrong . That’s my thought too maybe they defeated one sensor too manyTo eliminate or narrow in on the tune as the issue, have you considered reverting back to your stock tune?
If tune is issue, problem should go away if back to stock.
If the tuning was done properly, you have a hand held tuner which contains your stock tune.
Easy to dump it back in.
