Read the tune off.
Open scanner and start tinkering with datalogging.
With longtubes you'll start by adjusting O2 sensor tables to account for relocation of the sensor, which is generally further downstream. After that you'll want to work on adjusting your VE table then move onto fueling. There are a few other small tweaks, as well (cats, component protection, etc).
Post your tune and log in hpt/hpl format. Provide a description of all mods. We'll be able to show you better that way.
