FAST XFI questions I am getting all the parts together to drop my new LS6 this summer. I was debating on whether or not to spend the money on a FAST XFI ECU for my engine. I have to retain the factory ECU in my 97 C1500 to run the ABS, and splice in the new wiring harness to operate the instrument cluster. I can get the FAST wiring harness, ECU, and sensors for right around $2800. I could also run the LS6 ECU I have now with a new wiring harness for around $1000. My question is this. Is it worth the extra $1800 to install the FAST ECU? How much better is this system over the factory system? You should know that this engine with be FI with an ATI Procharger. Future plans will include replacing the short block with an LS2 408. If anyone has worked with these unit I would appreciate any advice y'all might have. Thanks
You really did not mention any specifics other than what the engine is and I cannot imagine that you would run anything with an LS6 that would require an aftermarket ECU.
Don't waste your money, spend it on a blower for the LS6 and STILL use the stock PCM.
