Hey Geoff,

It came and the 043 is set up waay lean.
Does your motor run good with this one?? I would think it ran hot and got great mileage.

Geoff,

I swapped the diaphrams from the 1.7 into the 2.0 just before i sent it to you. I did not install it on my car in fear it that it would'nt be calibrated correctly. My car ran fine before I got it back from powertech a month ago. The broken diaphram was diagnosed by a retired porsche mechanic afterwards. He did a temp. repair on it that didnt last. Im not sure how long it was originaly broken for. I assume it has been for a while, judging from the condition of the diaphram. Im really uncertian on what powertech F'd up on my car. They did manage to blow the side on my muffler. I replaced that with a bursch. Im real happy with that muffler. Some of the power came back, but not all. Still a dead spot from 1-3k rpm. Hopefully this repaired mps will solve the running problem.

p.s please include a diagram of how you run your vacume lines without the decel valve.

Thanks again,

Tod

that 'ill cost ya!

How about a blown out muffler and an all original classic nla fuel filter with 43,000 miles on it, clogged with sediment. The filter is a must have for any collector of these rare cars. It comes in grey plastic and would make a great restoration project for any enthusiast. Put that on your car and calibrate it
