Bad IC pump.

thank you. is there any kind of pump that you would recommend.

I have the K2 setup, 19" weds bavoria, 20% tint all around. thinking of getting the sprint booster.

Check your tires and tire pressure too. Stability and traction control cuts me down real bad if my tires are near bald or if the rear tires are running significantly different tire pressure levels. If you can find a very long and open lot in Mexico, turn on dyno mode, go from a slow roll into full throttle and see how well it picks up after the initial wheelspin.
