Refresh my memory. SLP is associated with Pontiac. Is it associated with the Firebire or the Grand Prix?
SLP caters to performance. Be it Camaro/Firebird (when Dark Age and I met) and now Mustang, Corvette, GTO, GM Truck, Impala and probably others. They at one time had a message board where a lot of good info was exchanged.
