Peak Gains: 181rwhp/137rwtq

Gains at 5900rpm: 185rwhp/167rwtq

Gains at 4250rpm: 104rwhp/129rwtq

Cant wait to see how he runs at the track. Maybe a new 5.7 stroker record in the future.

The red line is the same customer when he was heads/cam/bolt-ons. We gained 90rwhp and about 50rwtq over the heads/cam setup.
