You have the wrong resistors or you got them too hot when you soldered them in.. go to the local radio shack and get 9 - 10 ohm resistors, they can be anywhere from 1-10 watts. I like the 1 watt ones because they are smaller, cheaper and they work fine. I had them in my car for over 3 years now with no problems. Also if you over heat them trying to solder them in you will kill them and they won't work correctly once they get hot from current passing threw them....

I have the same problem on my FD. The exact same problem - except I have stock injectors and just a downpipe/midpipe combo with a Geforce ECU. I've gone over the factory service manual troubleshooting section twice over, and have no error codes. I'm starting to think it's the MAP sensor.
What sucks is, the factory manual doesn't have a troubleshooting section where the problem is temperature dependant. I really can't put two and two together. The coolant temp sensor is fine - i even swapped it out for a second one I had. I posted on rx7club about it, and all I got was a lecture about the apocalyptic dangers of revving a cold engine.

Ok just my two cents here. I am not sure how the injectors go into the manifold/engine on a FD but on a FC since they are top feed they have a O ring around the bottom and after a while that O ring gets hard and is no good. In vacuum it will run fine because the vacuum is pulling down on it......the moment the car makes boost it leaks around the injector and the car stumbles....bogs, farts and just runs like ****.
Now I know FD has side feed injectors and all but it could be something similar to that problem, something that is purely mechanical and not to do with the Computer, sensors and all that. I think it is worth a look.
