Had some issues with this motor after install.
Mods are 3 inch exhaust and 440's. I had 370's in there but still had the same problems where AFR's would go straight to 10 during full throttle within a few hundred RPM.
Motor is fully stock with stock twins. I think the 3 inch exhaust really threw off the fuel because of their fast spool with the 3" exhaust. The acceleration was really bogged down and surged a little both 370 and 440 injectors.

The first run at 13 psi the HP was 218 estimated at the flywheel.
After tuning with a used Apexi AFC Neo SAFC2 the car runs great and has 284 est at the flywheel.
This dyno run was done by the mechanic, I wasn't there. When he told me over the phone the results I was really excited and after I saw the sheets I was WTF!
After reading online about this type of dyno, they have a shootout mode which takes the WHP and uses a formula to come up with flywheel HP (est) from WHP. I really don't see how accurate this type of dyno is as everyones drive line is slightly different so it looks like I will have to check it on a dynojet and get HP and Torque, then save for a single setup.
