To get the LMAF to work your going to need a tune. So no. You could drive up there with the old stuff and change them over at the dyno (unless your going to be running alot of boost and you only have the stock inj. and maf).
You might need to get a trailer to get it too the dyno otherwise, or see if the tuner can send you a "very base tune" that will just get you to the dyno that has a maf curve for the LMAF and inj. slopes/breakpoint quicky to get you to the dyno? That shouldnt be too hard as the factory LMAF transfer is known, and a quick 1.2 x inj. size will get a run-able tune.
