My rev limiter seems to be set below the shift point at WOT, is there a way to verify/change this? Can tunercats do it? I have the cable already.

 

Yes it can, Using the Fuel Cutoff and Fuel Resume constant setting in TunerCat $EE definitions. Did you convert the 3.42 rear, if so you'r real problem could be your shift points. Assuming stock wheels, your signature says A4 tranny if so your original rear was a 2.72 and it has a stock 2-3 shift at 93 MPH you need to lower that to around 73 MPH (5300 RPM) with 3.42's. The stock 2-3 shift at 93 MPH shift is now 6800 RPM with 3.42's. A little high for stock block , IMO lowering shift point -AND- setting rev limiter from stock 5800 to around 6200 makes better sense, assuming your block is stock..
