I've got a question for you Andy. I have a supercharger on my 3.5, and am worried about running too lean and blowing up the motor. Is there a way to see just how much "headroom" the injectors have by checking the long term trim value you mention above?

A while back, there was some talk about injector size for our engines. Is it true that they are only 200cc units? This seems a little small compared to the 400-550cc injectors they're running on Hondas.

A local tuning shop told me that they could "splice" an aftermarket AFC unit into my PCM and get me the adjustability to run higher boost (more fuel). Is there any way to hack the OEM fuel maps?

I wonder if Isuzu ever thought people would be hot rodding their motors!

Thanks for all your valuable knowledge.
