Insight Needed: Datalogs Inside
Datalogs:
http://www.mediafire.com/?dyqyydmm2rn

These are all the datalogs I took of my car. The second link is a .csv file so anybody can look at it; the other two are .uni files.
The Car:
-1994 Camaro z28, ~138k miles on the odometer
-Stock A/C Delco plugs, ~6k miles since replaced
-Taylor ThunderVolt 8.8 plug wires, ~8k miles
-MSD Pro-Billet Distributor, ~8k miles
Modifications:
-Edelbrock Mid-length headers, no A.I.R, EGR is still hooked up
-Open Y-pipe
-BBK 58 mm TB
-Ebay CAI
-Descreened MAF
-TH350 with 3k stall
-Wait4Me Performance mail-order tune
-Powerdyne Elbow
Symptoms:
-Bad hesitation from idle, meaning I can go full throttle but it takes a few seconds before the car actually takes off.
-Surging on deceleration. Jumps RPMs in increments of 300 to 500 RPMs.
-Just an overall lack of power. I dynoed the car back in November of last year, and my best pull was 204 rwhp, and somewhere in the 240 range for rwtq. This was on a DynoDynamics dyno, SAE corrected (I believe).
Recent Maintenance:
-Replaced the air filter.
-Cleaned MAF with MAF cleaner.
As I said above, the car dynoed at 204 rwhp, 240-something rwtq. A/F Ratio during the dyno pulls was fairly normally, nothing alarming to the dyno operator. I have the dyno sheet if anybody would like to look at it.
The best time I have gotten out of the car was a 14.1@94 mph, on a cold October night.
I have owned the car since 2005 and have only put about 10k miles on the car due to many issues (opti and transmission, mostly).
I am just looking for some insight on where to repair/replace, or if the car is just in need of a rebuild. I will try to ansmwer all questions to the best of my knowledge, if I need to do more datalogging I can; if there is something particular you are looking for.

If I am reading the first one right, when the motor is idling around 650, the IAC position is zero. That is a problem. Should be 30-50 or so. Your TB is clearly not adjusted right. You might want to put your stoker back on, you are getting nothing from the 58mm with your mods.
