Idleing Issue / Question

[KidCapri50]

I just got tuned at BBR and they managed to peg my LMAF with procharger at 4000-4500rpm and stoppedat 370rwhp.

Car runs great except for a slight "surge" at idle while stopped. It isn't a miss I checked the coils and replaced plug with motorcraft gapped at .035. NO change. Could this be the maf? or what?

I would think so.....if it is pegging, then it would run wierd. What size injectors are you running, and what MAF?
