Dyno's are a tuning tool. You will get different readings from various providers.
You need to focus on before and after results along with driveability of the tune etc.
My non Jeep car makes 295kW ATW on one dyno but multiple power readings on the same dyno have in between 288 and 299.
I did a run on someone else's dyno and got 320kW ATW
If you're just focused on the # I'll give you names of high reading dyno's

i tried a dyno tune and the car was undrivable after 30 mins , has a long gear change like ridding the clutch and it was slower 0-100 times as well.
i might sell it and buy a camaro ZL1 400+kw
