Rockers installed, computer learning issue? (PROBLEM SOLVED)
I just put my rockers in, took it for a quick spin and at 5700 RPM it bogs down hard and pulls up to 14* of KR. Does the computer need more time to learn to put more fuel? I was thinking valve float, cause I left the stock springs, but it revved to 6 grand no problem before. What'* goin on with my car?

Only with the modified stock rockers can you run stock springs. If you have rollor rockers you need springs. You could rev to 6k before cause you didn't have the lift you have now.

When you rev to 5700 rpm, does it fell like the motor hits a brick wall and will not rev any higher, or is it more of a gradual powerloss above 5000 rpm.
If it suddenly looses power, but continues to rev at 5700, you've probably got valve float and need stiffer valve springs.

The computer needs more time to learn.
Mine did that when I first installed the 3.4" pulley. I was so anxious to discover the new power, I went out right away and tried some full throttle burns. Yup, like hitting a limiter. The Intense reburn helped as well by richening up the fuel curve a little.
Glad to hear that you finally installed those rockers. They will gain you a few tenths. :P

Yeah, it'* like hitting a wall at 5700 rpm.
