For bolt on car there is not really much done to the tune. Adjust your LTFTs with the scanner to make sure there within -5 to +5, Then command your AFR to a 12.5 to be on safe side (Fuel multiplier 1.175), You want to verify it with a wideband if posible. Them jsut adjust your timming to make sure there is no KR. Check the sticky on the section.
This is assuming you have HP tuners. All cars are different so dont assume a tune that works perfectly with another car will work great with your setup.

First things first, get a wide band, then for bolt ons, you can get away with recalibrating the maf transfer. With the bolt ons you have, all the VCM knows is that the 02s are reading lean, so it adds fuel. By re calibrating the MAF, you will be allowing the VCM to know exactly how much air is actually going through the engine, so it can accurately adjust fueling.
