  1. Finally got a v7 dash and a Link G4+ in my v3 wrx and was ready for the dyno. Keith Stewart is doing the tuning so bolted it up and the back hubs spun faster than the front . He made a good call that there were incorrect ratios going on. Must be when the previous owners swapped to the 4.44 ratio V4 STi box in my parts car, they left the original 4.1 ratio diff in there Put a proper 4.44 rear diff in and Keith got it tuned to 180awkw He was still having trouble getting it to hold rpm on the dyno, the controller kept getting confused as one minute power was 50/50 and then the next the car starts surging and the front hubs are spinning faster than the rear. We only managed to get a couple proper power runs after 4.5+ hours. My question is, has anyone experienced this before? Given ive done a couple track days with the car like this plus the previous owners kms aswell, maybe the centre diff fluid is so stuffed now it cant even keep them going the same speed.
