99 SS Dyno #'s
99 SS Dyno #'s Took the 99 SS to get dyno'd today. 27K miles, M6, 3:42 gears with MTI lid and Borla catback, running the plate just below wide open (according to Borla this plate gives the best TQ). HP was 299 and TQ was 312. The Dyno-Jet Graph is attached. A/F ratio was a constant 12.5. Got three pulls, the first was only 278 but the car had sat for 1.5 hrs before it was my turn. The next two pulls were identical at 299.

Your numbers are pretty comparable to mine. I made 296 with just a lid, I though my numbers were kinda low but figured with 118k on the odo, it must've lost some ponies through the years.My current bolton numbers are listed in my sig.These numbers are before the fra. It seems like the '99s tend to dyno slightly lower than the other years.
This Dynoed very close to my 99 SS m6. I just had mine done a week ago. got 293 hp and 314 tq. my mods are just a lid and 3:73's. I have since put on a Hooker catback and the car feels stronger. I may have it dynoed again to see what I picked up.
Does anyone have a explanation as to why 99's dyno lower??
