Hi, just fixed up my 89’ cabriolet and I’m having troubles tuning it. I believe there’s a different cam in it as it runs really lopey at idle and has aftermarket headers. Took it for a test drive and could barley get it out of the driveway without revving it to 2500, it also has an oil splash guard in the valve cover (I don’t know if that’s factory or not) the cam specs are, base circle 1.34”, 1.732” height, .406” lift (give or take) and has markings “G vwlogo 026 2d” on the other side just “G 8c”. also got around 185-190 psi on a compression test which is roughly 10 psi more than it would be factory spec. So it may have had some extensive head/cylinder work but the block is still stamped jh. Any help is appreciated! Thanks.
