[QUOTE="Black306, post: 7840308, member: 4780"] A modded FPDM is required with GT pump because GT pumps run with more current than stock Cobra pumps. Stock Cobra pumps will pull about 18A while GT pumps can pull 25A. Running GT pumps with a stock FPDM can cause the FPDM to go into thermal shutdown. I would personally suggest dual FPDMs over a single modified FPDM for a few reasons. First, a dual FPDM system will be able to supply more current to the pumps. A Stage 2 modified FPDM is capable of delivering ~25A of current, while a stock FPDM can deliver about ~18A to each pump. In a nutshell, this means that you'll be able to support more horsepower with dual FPDMs than a single modded FPDM. Next, if you are able to do the dual FPDM harness yourself, it can actually cost you much less to go duals. Thinking about the absolutely cheapest way to go duals, you only need one additional harness (wired with the factory harness; ~$30 new, less if found in a junk yard), a used FPDM ($40 or less), some wire (~$20), and a relay/plug combo (~$20). Not including a wire upgrade to the battery, since that would be a good idea with either a modded FPDM or dual FPDMs, going duals can run you less than $100. Even with all new parts and being more elaborate, my dual FPDM setup cost me ~$200. A deal on a Stage 2 FPDM is $235. IMO, the only real advantage to a modded FPDM is ease of install. [/QUOTE]
