There is no fixed amount you can add. Its based apon what the cam can handle and what smooths out the motor. With my Dynapack, I can hold the car at 800RPM, hold it at say .20gs/cyl, and meassure the power from the motor and add timing till you find the power stops and the motor is running smoother. This is the advantage to a dyno thats dedicated towards tuning EFI. But I can continue to do this as low as 400RPM and as high as I want.
The timing is something you have to just add and try. And if you feel like you added too much, just try it. you wont know till you do. Its the only way to find out.

Thats not a good thing. That could have been solved with some table work and timing. That hole will effect alot of your tables now.

Are you supposed to use the "Plus" button and add there?

Every cam is differnet, from what I can meassure on my dyno, no two cams will respond to the same timing in the same place the same.

Sorry, the tables are not for sale. I cant have tables floating around.

If you have a cam, I usually add more timing in the lower RPM band area. I can actually measure it, so every cam will respond very different. Some of thunders cams like their 230 cam does not like timing in the load areas, but only on light loads. So thats an example for you.
