First time on the Dyno

yesterday I made a trip up to a Performance shop in Hayward and got my car dynoed for the first time I was very happy with the results on my GT.
It was dynoed on a dynojet and it pulled off 284.1 Rwhp and 309.5 rwtq on a 87F day,as a full bolton and cammed 2v .
For that run I had an intake, Tb+plenum, Jba shorties, Slp xpipe, Magnaflow cat-back, CMS stage 1 cams and a mail order tune from MPH.
I was pretty happy with those results and as soon as my car was off the dyno I bought a set of steeda underdrive pulleys and had them put on :D. I had been trying to tell myself I would stop after being full bolt on but I don't really see that happenening haha :nono:
