when you say "surge", what do you mean exactly?

prost632,

Did you recheck the ignition timing after installing the 8973? Make sure that you do this as the timing will change between the two. The only way the ignition would cause a surge would be if something timing related is programmed in the unit. I would recommend opening up a default file change all of the parameters you are using this way there is not a chance of something being programmed in the unit. Has the car ever run with the 44 installed or is this a new installation?

Thanks,
