I sell both systems. Right now gen 7 has a CLEAR advantage over the fast. I work for ramchargers and have the advantage of great customer suppurt with both products, and plenty of people to bug
While i leaned towards the fast at first, i saw that the GEN 7 was going to give me the best benfit vs. cost.
GEN 7 INCLUDES: Brand new complete engine wiring harness, narrow band 02 sensor, 2 bar map, 2 coolant sensors, an IAT sensor, software , calmap cable, and an ecu. THIS BOX COMES SEQUENTIAL at no extra charge. Software includes a data logger, a BOOST BUILDER (in the 7 plus), built in 2 step, VE software, and a 3 stage n20 controller. It will also control all of the following: A/C clutch disable, coolant fan, fuel pump, and TCC ( im using my tcc output to control my gear vendor overdrive) .
Additional benifits with the engine wiring harness include the ability to go from one vehicle to another. Tired of turbo buicks and want to run a n20 mustang? no problem. simply unhook the injector and ignition adapter harnesses, purchase the correct adapters, move harness from one vehicle to the next, remap software and you are done. There are also outputs such as shiftlight and the above mentioned controlled functions.
Wide band is an extra 900.
A similar fast system is 3500 when converted to sequential, + additional cost for a data logger , ect.
The plus isnt a "fix" for the gen 7...just a newer version.. remember its almost a year old now.
