I know some people like thier car at about 11.7 to 11.8 and I'm not sure if that'll make that much of a difference to go and buy one.

When I post times you know that what every my car runs it's on ol' 93.

Pump (93):
Best ET - 12.644@106.04 1.748 60' (Flat timing in 4th gear = weak mph)
Best MPH - 12.698@107.21 1.795 60' (Last run on pump I had just finally figured out how to get my timing to start advancing some...even on this it didn't go above 14 in 4th)
Best 60' - 12.654@106.26 1.711 60' (One of my great runs that fell flat in 4th from bad tuning)
Best 1/8th ET - 8.024@84.57 1.711 60'
Best 1/8th MPH - 8.132@86.31 1.774 60' (No clue how I hit 86 on this one, since my trap was only 104.76...)

Mixed gas (4gal 93/4gal 104)
Only got one run - 12.344@110.71 1.789 60' (Culmination of finally figuring out my timing advance along with some higher octane. Didn't get a chance to run at this power level a 2nd time, otherwise with a 1.75 60', it would have been a 12.2x. I also hit the rev limiter in 4th 2 counts before the finish line, so it should have been 111+ if not for the stock rev limiter)

The most valuable tuning lesson I learned tonight was not to focus on O2s first, but rather timing. I was getting a good AFR, but my timing was flat. I had to richen it up some to get the timing curve back to normal in 4th. I didn't understand that my tuning was now different with higher boost due to the different timing maps my ECU was choosing because of the higher airflow levels. Now I know...
