Honestly thinking about it now I would just do it all as one job. Not really same area of the engine but at least you're only tearing things out of your engine once you know. If I were you I'd also go ahead and add the M air filters as well since you have to remove the front air box to plug in the racechip.
Crap I just realized you said flash tune.
