Saturday’s dyno tuning results

Canadians Vinnie and Hoppy drove through lake effect snow in S Ontario/ Buffalo this AM to ensure optimum performance on their F7s.
They had essentially stock F7s, one 04 one 05 with .010 nipped off their heads. Both had DD F8F9 Monster single pipes with large ZR900 diameter outlet pipes.
We began with Vinnie’s sled– after we dialed in his booondocker box it still seemed slightly low on HP considering A/F ratio and his offeset key etc. I’ve dyno’d 100 of these  Firecats and this seemed off the mark. So we installed a DD F7 Monster Single and picked up a solid 4 CHP. Fine tuning Vinney’s sled we wound up with 152 canadian trail-safe HP assuming he can maintain cool coolant temps.
Next Hoppy’s sled, F7 identical to Vinnie’s but the Boondocker I provided him had my dynotecch map.
we tweeked fuel flw for a while, when we were done with my trail safe map Hoppy had 152 HP just like Vinnie’s . But both Bondocker maps were totallly different. Vinnie has DD program, Hoppy had DTR map wirh zero overlap A/F ratio.
Tomorrow a Fusuion turbo- Dialed in on our dyno.
