I took my car to the track for the first time since most of the mods listed in my profile. The tuning isn't the best since all I'm using is a translator and a logger, and I didn't really even make any adjustments yet. My boost was at about 22.5 for the first run and 23 for the second. Keep in mind this is on 93 octane with stock cams and no real tuning.

1/8 et - 8.086

1/4 et - 12.488
1/4 mph - 111.09

Reaction - 1.380
60 ft - 1.871
330 ft - 5.236
1/8 et - 8.019

1/4 et - 12.430
1/4 mph - 110.56
I realize my reaction times or 60 foots weren't the best, but I'm working on it still. The thing that really confuses me is the 1/8 mph difference between the 2 runs since my 1/8 mph went up by 5 mph!!! The one with the faster / higher mph 1/8 mile was with the extra 1/2 psi, but then it seems it fell on it's face on topend. I am tuned pig rich ( .98v using O2 sensor 1 ... I know it's not the proper way to tune, but I just wanted an idea where I was at so I logged a 3rd gear pull and that was on a cold night a few weeks ago ) however my topend still sucks more with more boost. I think this means the most amount of boost I can safely run on pump and I should tune for is around 22 psi then since at 22.5 knock was almost none at that level? Are these decent times considering I'm on stock cams, pump gas, and tuned pig rich on a larger size turbo, or should I still be going faster? It seems to me it's just a tuning issue, but I was aiming for a high 11 on pump and trapping at least 114 or so. Is this possible if I just lower the boost to 22 or so and lean it out and get faster times out of it? Any advice or input would be appreciated. Thanks.
