my mate about 2 years ago, ran 176 whp on the stadard ct9 with an emanage, so it can be done with a proper tune, the RRFPR FCD will be a fine setup, i have a mate with a gt who run around 193 fly power, with that setup, no fuel controller nothing, just had it set up correctly at a bar of boost so it can be done only thing i would watch for is the ep91 conrods are not as strong as the GT ones, i await people arguing there is no proof etc, but they aint there made from the same material, yet ther not as thick, therefor there not as strong, end off lol i will have a RRFPR and HKS FCD setup(i would have this one over JAM/GREDDY as they cut after the fuel cut, where as the HKS reduced the voltage output over the whole range, so done properly with a RRFPR and a SAFC to bring the fuel back, it will keepthe car fueling within stable AFR range over the whole range, whereas the jam greddy etc, only cut over the fuel cut level, so below the fuel cut, in theory, they will run lean, which is never good
