Im piston knowledgeable but..... 550's are fine primaries, and you 2nd's you can tune some fuel out. If your new to this turbo stuff you may want to consider letting somone with experiance tune your car. Im not shooting you down or anything but this is something u want to make minimal to no mistakes. If you are tuning your car yourself just take it slow and ignore the WOT urges! also use a wideband
