WOT tuning

I'm about to do some WOT tuning on my Z28. I was just wondering if all you need to change fuel wise is in the % enrichment table, or will the VE table @ 100kpa have an efect on the fuel too. This is on a Turbocharged LT1 running 10psi with 42# injectors. I have been changing things already but just wanted to get someone's advice who has done this already.

Bill,

From everything I have read, it is an argument whether VE tables are used by MAF run cars in closed loop - I assume you do not have a 93.

My personal feeling is that MAF operated LT1's do not use the VE tables at all in closed loop. I have just changed coolant temp. PE tables and that is it to adjust for WOT conditions.
