And what wide band does it have?

[williamb82]

id have gone with a maft pro. but as mentioned before, youll need a wideband in order to tune the afr's. id tune for 14.7:1 under vacuum, with maybe 16ish:1 at cruise. then under boost id run 12.5:1 afr until ~12-14psi then drop it down to 12:1 afr. im guessing your on stock 10:1 compression since you dont mention using a tt headgasket or swapping pistons. youll likely need to retard the timing some as well to prevent damage. the maft pro has the ability to adjust timing btw.
