I got back from the rollers very unhappy. First the motor made 349rwhp at 5900 and 362rwtq at 3800. I was sure that the hp would have been around 375 or so and the torque would have been another 10 or so.
And now the big disappointment. On a 125 shot it made 549rwtq, which is around what I thought it would be, and 429rwhp at 4000. As the rpm went up the hp went down, ending at 300 at 6000. It let out a huge backfire at the end of the run. This was with 57 and 33 pills and good bottle pressure. I really don't trust the a/f monitor they have but, it was saying 11.5. I will hook my wideband up Monday and see what the hell.
Anyway, a huge let down.

 

I hope the backfire was out the exhaust I'm guessing it was if you still have an intake manifold.It sounds to me like you are running to much timing.

 

If you are losing power as the engine rpm goes up then it sounds like a fuel system issue. Maybe you need new fuel pump or injectors? Check your spark plug color to see if your engine is running lean.
