Thanks

don't know anything about cables and horsepower gains, that seems like a question for one of the tech gurus.
no change in idle with the new chip, the directions were simple and brief and so was the chip swap.
all you have to do is remove the computer from under the seat, carefully pry off the metal cover and open up the mother board. if you have an early 87 than you might have a 24 pin chip, seems porsche went to a new mother board during 87. my motor came from a later 87 model because it has the 28 pin chip.
I have not had the car dynoed so i don't have a clue about horsepower differences with this chip over the stock one, but it really does run much better than before and is loads more lively. nearly spun the car last night shifting from first to second up hill in a spot that I have driven many times, so the power is much more available right now with this chip.
it is 33 degrees F today and the car starts just fine and has no issues yet.
it will be in the fifties during the week so I will get a chance to see how it performs in a little bit warmer weather.
still no sign of knocking or pinging.
