Do either of you have dyno charts or figures you can post?




I have a summary page I can post. Numbers are not at all impressive. Some things Wayne at Power-Tripp determined seem to make a lot of sense. Traveled ~250 miles one way for custom TuneECU fuel mapping. After some tuning it was determined that my left & right side fuel injectors are not working the same. Had to basically tune for the left side cylinder and de-tune the right to match. This shows max 59.5BHP and 50.9Ft/Lbs of torque. Overall I had gains of 10BHP and 7Ft/Lbs of torque over stock, or before engine & air box mods anyway. Again, I am very happy with the current state of performance.
09 EFI America mods: no snorkel, air inlet enlarged to ID of UNI filter, internal restrictor plate cut away, 813 cams, 904 big bore, 17T front sprocket(from stock 18T) and modified TOR exhaust running on mid grade fuel.


09 America, some modifications
