I've got a TOMEI EL header, and using OFT v4.3 Stage 2+ at the moment, but from what I read on the forums, it seems the v4 Stage 2 has the AVCS of v2 EL tune, while Stage 2+ is closer to v2 UEL AVCS.
The only difference in v4 between Stage 2 and Stage 2+ seems to be the AVCS and Primary Open Loop Fueling tables.
So, for a decat EL header would it make sense to use Stage 2+ (which is for decat ) but with the Stage 2 AVCS ? Or same thing, the Stage 2 tune (EL) with the Stage 2+ POLF table (decat) ?
