Based on other posts here I will not need it since I just have one fuel pump and a BAP. Since you are looking to do two fuel pumps it is required for your voltage.

I copied this from the Lethal Performance web site
WHEN DO YOU NEED IT?
If you'are running a pair of big returnless fuel pumps (i.e. Lincoln Aviator, Ford Focus, or Ford GT) and/or running '03/'04 SVT Cobra dual pumps with a pump voltage booster in your high-horsepower Mustang you NEED to have your FPDM modified. This modification allows the Ford Mustang driver (99-04) to sink substantially more current (up to 25Amps) without overheating. What happens when the stock driver overheats? It goes into thermal limiting and cuts ALL fuel supply to your engine until the driver temperature drops below a safe level. As I'm sure you're aware, the loss of fuel pressure with your engine at full load can often times be catastrophic!
This modification will NOT require a retune of your vehicle. It will not reduce reliability of the driver or of the system. In fact, the driver will run much cooler than in the stock configuration which will prolong its life even when used with high-flow, high-current dual pumps.
WHEN DON'T YOU NEED IT?
This modification is NOT necessary if you are running stock '03/'04 Cobra dual pumps without a pump voltage booster or a single Aviator, Focus, or Ford GT pump without a pump voltage booster. It will not hurt to do this modification with the above mentioned systems but it is not necessary as those pump setups all draw less than 18Amps at full load.
I bolded the part thats important. You don't need it when you are running a single pump without a voltage booster. Based on the fact that it specifically stats without, one can reasonably deduct that with it you do need a modified fpdm.
This is my plan. I am going to run dual cobra pumps, w/o a BAP which are good for 460-480 rwhp. Then, when I have the money and get bored with the power I can throw a BAP on it and upgrade the FPDM.

I am going with 1 Focus Pump, BAP and targeting 480-500 rwhp. I just need to confirm my build weekend with my buddy. Let me know how you do once completed.
