This wont apply to your setup but I have a spare set of injectors with the pod for my TBI setup. The pod is set to 30 psi not the stock 15 and the injectors are tuned to match. I still need to get a spare ECM with chips ready to roll.
On the radiator, except for the lower efficiency in the transmission cooler, the Aluminum one I just installed is working fine. The external cooler took care keeping the tranny fluid in range
Do not take life too seriously.
You will never get out of it alive.
