Hi, My 1993 obd1 pulled 152 at the wheels on the same day as my mates highline did 148 on TSR dyno. I've never heard of the later cars supposed to have 193bhp either. Can't see why leather heated seats or colour coded bumpers would give you more power. Another friend has a 97 non highline that pulled max power of 186.8(flywwh) on the AMD dyno with a shrick VGI and miltek cat back. All dynos vary but I'm pretty sure the base line figures are the same for all 2.8VR6 motors. cool website.
