i ve done a nice project, i installed a tpc supercharger on my 964 1991, controlled by vems ecu,
all was going good, but suddely i realized that the mixture is too rich on idle, and that on deceleration from high rpm, the mixture is rich (10) i realized that the vaccum is not going less than -0.5 which is strange, i checked all vaccum lines there is no leak, is it possible to be fpr? does it affect the vaccum?
this problem happened suddenly!
i will be glad to hear from u guys

Hi.

Please provide a log of the occurance,
I don´t know what you mean by -0.5 ,

you FPR could only affect vacuum readings if it was leaking air pressure

vacuum i read on Idle is 70 PSI, on deceleration minimum is 50 psi!!! i will check the FPR first easy work :)
