Please see my video above .I ve decided to find help somewhere else. Cause unitronics has not replied my message. And my mechanicstatesitsnormal.
I have a 2006 audi a3 2.0 fsi. Mods: downpipe, neuspeed intake, forge catch can, k04 turbo, s3 injectors, s3 intercooler, godspeed twintercooler, autotech fuel pump internals, bsh throtle body, awe dv relocation, forge dv, unitronic 2+,
My issue is. When accelerating gradually ( not flooring it ), in any gear , when going through 2900 -3800 rpms , the car starts building boost and I feel a drop in boost momentarily, followed by a raise in boost. Happens in all gears,causing in ocassions the car to jerk. If i floor it the drop in boost isntnoticeable,but at times I can hear a surge or flutter sound that goes away by 4000 rpms if floored
I need ur help! Ideas!. I ve also read threads about possible solution, where Apr states boost is too high at those revs. And Revo states tweaking wastegate solves. I had revo 2+ before going k04, never had hicup. Decided uni for k04.
I switched dv between from forge to rev b and still the same.
No codes! .
