Depressing Dyno...

[Grn92LX]

Looking at that graph, its very jittery up top. You said it your self that the engine has a miss. Now, you have to do some checking/testing to see what is causing the miss. What ever is causing the miss is causing you to lose power. I'm no expert, but i've been in your shoes and it sux. It sux when u have all those fancy parts and somethings wrong causing u not to get the most from your combo. Are u getting good spark? Fuel? Do u have a fp gauge that u can see at all times, preferably a cowl mounted mechanical one? This way u could see if fp is dropping.

I had a problem with my combo. I went to the dyno and only made 275rwhp/316ft/lbs and I was like WTF, My combo should be making more. Just recently I found out that all along my fuel filter was on BACKWARDS!! This was causing my bad dyno #'s and track times all along. I havent re dynoed, but I did gain a full 3-4 mph at the track which is a big difference for just a filter. My graph wasnt jittery like yours, but I did only make pk power @ 5100, which is low. It fixed now, just needs some tuning.

I agree with some of the other guys, that B303 cam isnt great, but its not the reason for your bad #'s. You have a miss and you have to find out whats causing that miss. Good luck man, I know how it feels!! I'm glad that it only cost me $10 to fix my combo, I hope its just as easy for you!
