sounds like overboost. I've gone from knowing nothing about this subject to being an expert within a month 
What mods do you have on the car?
What happens is: you get to much boost, the ECU cuts fuel, then it kicks in again.
My car has an adjustable bleed valve and I was experimenting with it, I managed to get overboost cycling in and out bwarp-buhh-bwarp-buhh-bwarp-buhh which is not good (although the guy in the 300ZX I was overtaking found it hilarious
)
