I dont know alot about CIS but i woudl think that would provide really high fuel pressure?

or maybe really low?

a car I am looking to buy has this done to it... I would put it back to stock with a new FPR but I nwat to make sure that the engine wasnt damaged because of it being run that way.

Thanks in advance for any onfo.

if it was running particulary too rich then you "may" see some loss of compression.

But otherwsie, no it shouldn't have caused anything significant.

Do a good check and be thorough though. I have found that if one thing has been "rigged" there's usually something else that's been tinkered with.

under the car, which is no biggie.

I will be doing a compression check anyway though.

and I plan on having to replace stuff anywho.
