Update on my 2011 Z06.
Took a detour driving back from Sebring to Connecticut last week to go back to Katech for new valve springs, check up and dyno.
When Katech did the Stage 2 three years ago it made 540.6 WHP and 467.3 TQ.
No changes were made to the car since it left Katech three years ago. Since then I drove it about 23,500 miles.
Last week it made 539.3 WHP & 476.2 TQ (no headers, full stock exhaust).
I want to thank Zach for being able to squeeze me into Katech's busy schedule last week.
#100 has been running great for the last three years and is ready for more!
On the way to KATECH my 2011 Z06 easily passed the C8R.
