You just won my business with just a few words.We have some new files available.
In general: ANY tune trying to run big mid-range torque can see compressor surge, (this is not isolated to any vendor).
The effect can have some to do with driving style:
Full load at ~lower revs and high gears is where you see it. Calling for ~too much pressure for current compressor flow.
If the boost curve is optimized for 6th gear to completely avoid surge this may seem
like 'slow spool' in lower gears.
If the boost curve is optimized for 3rd gear, you ~may drive into surge in high gears.
'Low boost' files avoid this altogether but tend to produce less peak torque.
Its interesting: these ecu's have anti-surge limitations built in. We did not cut/go around/or otherwise remove/tune
this fucntion out, yet surge is occurring in some cases. Change intake parts also plays into this.
Anyone who believes they have compressor surge running UM software:
Please return to your UM dealer immediately: we will address the issue. Absolutely no cost.
This will NOT be: choose one of two choices. We will sort you individually.
