No , you dont need to go to a dyno , you have a tune that is a best guess , cookie cutter , off the shelf , you need to send datalogs to your tuner and get adjustments made to make the custom tune you paid for , they should of asked for datalogs , I ask all my customers for datalog to get them the best tune they can get , you could be giving up 0 to who knows how much HP and engine safety as well
EVERYONE should be sending datalogs to there tuner to get a custom tune , no 2 Foci are the same so the base tune file is just that a base tune file , if you dont have your tune checked (datalog) how do you know its safe and doing all it can do , thats what you paid for , right ?
Your tuner should be giving you a list of things to datalog so they see what needs to be seen to make the proper adjustments to your tune
