The hydraulic clutch option with the TTS kit is nice, I have it, it does away with lifter piece which is a bonus.
Power is all useable with strong torque lowdown.
Naturally aspirated tuning gives similar bhp more rpms but torque is moved up the range.
Depends what power you want, stump pulling stomp roll-ons or arm stretching acceleration up to giddy rpms.
I added S/C to my tuned motor 4years ago because torque was 187ftlb @ 5.500rpm, 2000rpm only 153ftlb
I didn't want to have to change down to be in the power band.
It has it all now.
