Fuel Table question
 
Camaro lt1 stocker.supposedly really good heads, all top notch parts. fast xfi 2.0, timing at 36 degrees. My question is what should my top rows on my fuel table read at wot. These are my numbers. At 4000 rpm and go to 7500 rpm increasing in 500 rpm increments..130-158-186-196-190-188-186-177. Fuel pressure is 60 lbs Just new to fuel injection. In alpha N mode. I might should switch to speed density. some people say is less confusing. Is that true?

Get a wideband and you'll know for sure.

Should have come with a wideband. If you don't have one, you need a data logger so you can play a run back to see what your actual air/fuel ratio at each 500 RPM cel in the fuel table. I use the FAST internal data logger.
A given set of numbers in the fuel table won't be right for every LT1 Stocker. Different cams, injectors, fuel pressure, headers and cylinder heads.

In AlphaN mode, yours will be different in different weather, and at different elevations.
