I did the C4 swap and nothing else beside a retune. Everything else was the same.
Old 4R70W combo:
DirtyDog Performance 4000rpm stall Converter (reworked PI converter)
282rwhp and 304TQ (locked converter)
New PA C4:
DirtyDog Performance 5000rpm stall 8" converter
280rwhp and 367tq (no lockup)
The only thing I did different was the trans swap, no other mods. Both combos have 29 degrees of timing and a/f 12.7-12.9. Of course these TQ numbers are skewed by the TQ multi. and stall but I was really curious how efficient the converter would be being unlocked. It looks like it is very efficient which is what I was wanting.
The one weird thing was my rwhp peak increase from 6100rpm to 6500rpm. Not sure how the trans/converter swap would effect the peak rpm. Anyone know why?
Again dyno numbers means nothing on high stall converters, it is just a tuning tool but still wanted to share.
