Datalog Underboosting or something else

[30ff_335i]

Could someone please help me out while I'm waiting to hear back from my tuner. My car is pulling sluggish when I'm accelerating at higher gear only happens at 5th and 6th gear maybe sometimes 4th. I feel like the car is struggling building boost would spiked up also. 1-3rd gear is flawless pulls but not 4-6th gear.

I've link my log on datazap see if you can help me out what the issues. I'm hoping it just tuning.

Car on single turbo 6266 91 octane no port injection at this time AND still on basemap.

5-6th gear pull https://datazap.me/u/e92garrettz/5th-and-6th-gear-652021?log=0&data=3-22

3rd gear pull full boost https://datazap.me/u/e92garrettz/652021?log=0&data=3-22

This looks weird. Target boost is going up and down like crazy. Throttle closures all around... if you are not satisfied with your tuner, contact v8Bait. He is a Forum member and the best tuner around if you ask me.

So do you think its the boost leakage or it the tune?

I think its the tune. You said you are still on a base map? If yes, wait for the tuner to reply. Dont go WOT until then.
