I have a w plate pd 115 recently remapped by Storm Delevopments (massive power gain) but im not sure if i had this problem before the remap as only owned the car for a weeks and extra power may of made be notice my issue

1st\2nd\3rd pull on full boost foot to the floor no worries when i get to 4th\5th\6\th it coughs the boost will come off at random rpms mostly if i boot it from low revs almost like the gets to max boost the decideds nope that enough air them boost comes back on a second or 2 later

Changed a very new looking MAFF for a VW Gen part still no better

Could this be back pressure or turbo probs?

Any ideas guys

p.s i phone Storm and they was convinced it would be the MAF but new one today still no better
