96 GSR-T

got my car tuned last Wed, all went well, ran fine the next day as well, so i know my issues are not in teh tune, went and took a friend for a ride around the block, car pulled clean and hard through 9k+ in 3rd gear, made a u-turn and did it again, heard a little breaking up around 6k in 3rd but the car pulled through fine. Next day went out for a joyride and on both high and the low boost settings the car's AFR's are a nice 11.3-11.5 until about 5k in 3rd gear they start to drop and the car starts to studder and break up, by 6k and 18lb the AFR's drop to the 13.0 range. I hav checked and rechecked all wiring, grounds and fuel pressure is rising under boost, fuel pumps sound fine and are running. I thought for sure it was my Blue Earls filter that was the cause, changed it out for the correct filter and the problem is still there, plugs are gapped at .016-.018 and look fine, wires are MSD and are about 1.5yrs old. The dizzy is amazingly clean inside and is a loaner from a friend that also makes 600 on it, do not believe it is the dizzy but I could be wrong. I had some slack in my Timing Belt and I re-did all that earlier and got that back to where it should be, though by some crazy chance that might be it and it wasnt. I noticed I had under a half tank of fuel so I topped it off, still there. I would try another Dizzy but this is the "other" dizzy that I could get my hand on, is there anything else that I can possibly check before I fork out the money for a new OEM Dizzy?

Turbo-charged

nearly every time i have tuned a car and everything went well....then all of the sudden it starts freaking out like that....its pretty much always been the distributor or in the customers "rigged" wiring.

if your confident in your wiring...borrow a distributor and give it a shot.

Thanks dude, I am pretty **** about wiring, I use solder, liquid e-tape with shrink wrap on top. Plus I put over 1500 miles on this motor prior to turboing it to make sure all was well. Only area I have skimped on is I used connectors for the Resistor Box and Map so I could return back to stock to get re-inspected, think anyhting in there might be the cause?

There is a sponsor in teh markerplace that sells "TEC" Dizzy's, I know OEM is a TEC also, has anybody used these w/o problems? I know the King's tend to go screwy with EMS systems, but I am unsure of their producer.
