ok well i got my APR chip in the begining of may and ever since i have been having at little bogging problem. when in the 91 or 94 program and i floor it my car kinda boogs and looses power at the 3600-4200 rpm range, but im not losing boost. my boost styas constant at 15-16psi but at that range i get a little bog. im jsut trying to figure out what this is beucase it happends right in the sweet spot of the rpm range. could it be the inlet pipe colapasing under the pressure? or is it something more like i need to replace my injectors? i was told by a mechanic at the vw shop where i got the chip that it could also possibly be a coil pack. but the ohter thing is if in stock mode i dont get this problem and also if i take it easy till about 3200 or so and then floor it it doesent happen. please help beucase i want my car to preform properly so i can enjoy the chip
thanks

 

Sounds like the same problem I am having....do you have an automatic and is it doing this in all the gears?
