I couldn't find the 351/421 chart so this is 341/410

solid lines - BMS filters
dotted - filters + standback

I've heard conflicting reports about the filters - some say they add no power, some lose, some up to 15hp.
Hopefully soon I'll get a chance to do a stock box to BMS comparison. This is an auto trans btw and I think it was done in 3rd.
