Running MAP in the southeast, south, and southwest is much easier with it since its based off of a fuel curve that is programed into the ECU or Piggyback and it does not change. So basically, your fuel map never changes no matter what the air conditions are outside (dense, thin, wet, dry, etc). I don't know enough about MAP setups yet to do much more than sound dangerous, but going off what i have learned so far using your car for a racing application would easily justify going MAP since the car many times isn't a DD for most folks, but in this case it is his DD. He would need a 2 BAR Stainless Steel Sensor Kit which are over 100 bucks and then he would need to modify his piping or even replace a section so it is another investment for sure. IMHO if you are going to make the change and investment to go MAP then you are better off ditching the FIC to go full standalone since you are looking to optimize for higher boost and the FIC just doesn't protect your investment. It seems the FIC is for folks wanting to use low boost which traditionally won't put your engine in much for danger of blowing up compared to medium/high boost. 8-10psi is fun as it is on the roads so I would think that 15-18psi is more giggles for sure when at the wheel so being patient at that point rather than risk further time/money makes more sense. I am not sure what most would consider FI changing from a hobby build to serious is since it is subjective based upon the driver and the vehicle, but to me going over 15psi is getting serious.
