Hitting the dyno in 2 weeks !

yeah im pretty upset, but ill deal with it.
My engine started to ping at 5000-5300 rpm, so it had to be shut off at that point. The guy doing the pulls (Chris Tapp, owner) didnt want to blow my engine, so he backed up the timing a little bit and finally got one pull in without pinging, but said he didnt give it all, he let up early so he didnt hurt the car.
My one pull was 273.9HP@5250 (shutdown) and 292.3TQ. If you were to look at the dyno graph, HP was still going up when shut down, it really sucks.
Chris told me that i have to run 94 octane from now on (apparently engine cannot handle 91oct ?) and that i should get an adjustable fuel pressure regulator. when i do that, Then i will come back and get use of the wideband, and it should help. I am ordering the regualtor this weekend, because i want to go back ASAP to find out my real dyno numbers.
