Borg Warner EFR series turbos....

Are the BW maps comparable to Garrett's, or do they take their readings in a different way? That map you posted of the 68mm is 95 lbs/min, and a 4094 (67mm) is in the 80 lbs./min. The 4202 is 95 lbs/min with a much larger wheel. Or are the BW wheels that much better?

To many variables. The GTX's are UNREAL so far on the trucks we have put them on.
