Low O2's And Knock

[BADINBLACK6]

Nailed my TR from a stand still today pulled hard only got halfway through 2nd gear (short street) but I got o2's 538 and 3.8 kr. Temp 85* 93 octane boost 15-16. Both counts were at 50 mph.
Coolant temp was 168-170. So I drove up to a main street where I could get a 2nd-3rd shift. Nailed it in 2nd ran through 3rd to about 70 mph and got o2's 382 kr 1.9 and car started to buck and surge but it wasn't missing or popping. Counts came low o2's at 60 mph highest kr 53 mph. any ideas?

Damn whats your fuel pressure?? Is it rising with boost??

fp is set at 45 line off with the thrasher chip. Could a bad coil pack cause this. Haven't been able to verify boost and fp rising together, it's been raining since i posted this.

Probably not a coil pack. You need to verify that FP is going up 1# for every # of boost

Alright rain finally stopped. Verified fuel pressure 45 line off. Took car out to verify that boost and fuel pr. are matching. boost set at 16lbs 1st run 60-61 fuel pressure 16lbs boost, o2's 760 kr 1.9.
2nd run same o2's 773 kr 0.5. I noticed that while the fuel pr. rose it did not rise at same time as the boost, I was at 16lbs and fuel pr. was still climbing to get to 61lbs. 3rd run everything pretty much the same but at top of run car started to surge and fuel pressure wasn't steady and I saw 3.5 kr got off it right away checked out o2's 443/ 3.5kr. It didn't seem like the fuel was keeping up with the boost, could a bad regulater cause this I bought it used awhile ago, it's a stock appearing reg.
I really haven't driven the car in about a year and want to get it tuned so I can start having fun with it again.
