I am having problem after intake install on my 97 A4 1.8 TQM

everytime I hit over 14psi every gear, my car joggles as jackin motion
it happeded after I took the original airbox out, and installed cone airfilter infront of MAF
my boost gauge shows 14 to 10 psi up and down while it's in full motion.
funny thing is it doesnt do that if I put the original airbox in.
I know original box does all the job and I dont need intake for A4s but I like the spooling sound of it so dont point that out lol

anyone have same experience?

I'm not really understanding what you mean but my car never "joggles as jackin motion" before in my life(with or without intake) when in full motion.

Sounds like you blew your DV. Get a 710N and I bet that will solve your problem.

Are your vacuum readings normal at idle?

it surges as your DV is blown or somethin.
I have 710N valve installed 1 month ago so I dont think DV is problem. Vac is bit low, dont know the readings are accurate but it goes down to 30 hog when idle.
it's just that problem occurs with cone air filter.

Did you just mount a cone filter on the end of the maf housing? IF so what does this cone filter look like, does it have a flat end?

Well if you mounted that filter onto the end of the maf, then there is your problem. That type of filter(inverted top) will cause a dead spot at the maf if you mount it right to the maf housing. This is why your car goes lean at high rpms while on boost. You need a standard filter that has a flat top.

Something like this

A inverted top filter should ONLY be used with a CAI that has a tube between the filter and maf housing.

Better off just replacing your filter. When you add pipe you have to make sure there is a short straight before the maf sensor other wise the readings can be off.

it could be the diverter valve is busted or you could have installed your maf backwords.... hapens sometimes. check it.
