Good stuff -- thanks for sharing... Did your Butt Dyno tell you anything?

Test 2:
High 193.53
Low 190.45
Ave 191.93

Test 1:
High 189.51
Low 185.75
Ave 187.85

I still think that this is a bit lower than the expected ~195hp ave. If you look at the A/F ratio from the second test (top image above), it shows that the engine is running a bit lean. This implies that the cylinders aren't getting enough fuel. I had the fuel pump tested which was fine.

Then we pulled the injectors and sent them out for test with results of low flow rates in 3 cyls. This might be the cause of the lean condition so we had them cleaned and calibrated.

I'll get another dyno test to see if the injector cleaning made any difference as soon as the opportunity presents itself.
