Before and after TR230 charts
60hp and 15ft/lbs at the rears from a cam upgrade. I switched from the stock 241 head to a brand new set of Z06 243 heads when I did the cam.
The car had a different mail order tune for both before cam and after cam. I believ both dyno charts to be "corrected"

60rwhp gain is really nice. I wonder how much of that was from the heads? Ive been thinking about a set of LS6 243's for my car with a TR220 114.
