ohhh and when you said that you need 3BAR map sensor with turbocharged, well my friend with HALTECH said that its NOT TRUE.
1BAR map is for N/As and 2-3 bar maps for turbocharged...2 for lower boost and 3 for higher boost..15 above i think..

I don't want to have to buy another map sensor later, so I will spring for the extra $16 since I am spending almost $1300 already =) Why go half *** when I finally went with a real EMS! LOL

I'm not really following this. I know I should probably look in the ECU section, though.
Correct me if I'm wrong, but these are the options as I see them:
1. Get a terminated Haltech harness. This apparently has longevity issues. You have to run the new harness into the engine bay, but it hooks up to the stock sensors.
2.a. Get a flying harness. This means you have to run the wires yourself, and have to make new connections for your stock sensors.
2.b. The other option is to use the flying harness and instead use GM sensors.
3. Get a Haltech with the FC3 conversion, which allows you to use the stock sensors (except MAF, which requires MAP instead) and wiring harness?
Is this right?
Also, is there a reason most aftermarket ECU's have MAP instead of MAF? I thought MAF was more accurate, and allowed for small variations in VE.
Sorry if these have been answered before.

Perhaps you're thinking of the Typhoon/Syclone, which used a 4.3L turbo V6.
