Looking for local help.
I posted this in performance forum also, but thought some locals might be able to help me out better.
I had a problem for a while now that my mileage has dropped down to about 36-38 MPG highway 32-34 city. I've noticed that I get puff of white smoke at start up and I'm hard pressed to to get the EGT's above 800-1000F summer or winter driving. I use to be able to get 1000-1400F when I really hammered on it.
I read this post below and saw that Migbro replaced his injector and things improved. Has anyone else had this expierience?

Some additional info: I put PP520 nozzles in (uncalibrated) about 75-100K miles ago, I've got RC2 tuning, I replaced the T-stat due to low coolant temps (no change in MPG's or EGT's). I will be replacing the coolant temp sensor soon (I have it on hand) due to random alarm. I will be getting a compression tester soon to verify if its good. Recently replaced the glow plug harness, kept getting codes. Codes stopped after replacement. I need to replace the timing belt, this one has close to 100K on it but timing looks stable as found with Vagcom.
I wonder if there is another member locally (St Paul MN) that might be able to meet up and help verifiy that I am getting white smoke and not blue(bad valve seals or rings)? It's tough though because it only does it on a cold start up. The car would have to cool down for several hours after meet up. Maybe there is a GTG coming up I could attend?
