Karim, Thanks for the info,

Rcompart is a great resource for some of your questions. I thought you have a normally aspirated 55 which you have added the 55 supercharger. i thought you also used the n/a 55 ECU and are running the 55K engine program. If you used varient coding to select 55k and are using the 55K harness and correct sensors you should be fine as long as you are also running a smaller pulley to cut down on the boost since 11.0:1 compression will not take the regular boost levels of the Compressor. RCompart has experience adding a supercharger to a na engine and can help as well. I have seen people add a super charger and have to set the clutch up to be on all the time.
