Just put in an APR stage 1 chip on a 2001 1.8T. There is more power, but it comes on later than stock and is jerky in some parts of the power band. Any reason that this may be happening, besides diverter valve (just replaced that as well)? Isn't the APR chip *supposed* to be the smoother chip? Any thoughts are appreciated.

Thanks.

upgrade to the apr one or get a dts if u have a manual... do u have an aftermarket DV or just stock?

Did you do a throttle body adaptation on the engine when it was *cold*?

nauticacomp

i thought it only worked when u did it while it was "cold"

Then it tapers down.. So yeah its pretty damn jerky when that 240ft/lbs of torque hits.

I don't particularily care for the tuners remapping the torque (floorpedal) either. Its rather annoying to press 1/2 way down and get 100% throttle.

Those two things are probably why alot of NON-DBW dis the DBW, and quite frankly, it is purposely done that way to give the "fastest" feeling.

Replaced that as well, but don't think it has anything to do with the jerky performance of the chip.

Car couldn't have been colder.

is your ac on? i notice some surging when my ac is on. nothing drastic, but noticeable nonetheless

Ring-Go

Yes, more pronounced with A/C on, but still very noticeable w/out A/C running

noticably weak with the OEM chip.
Also look for boost/vac leaks .. bad hoses and or connections etc.
