So spending money on a higher flowing fuel pump also is not necessary.I would like to know how old the car they carry out there tests on is? APS discovered that the fuel pump performance actually deteriorates quickly within the first 6 months of use and then it seems to level off. I would hate to buy one of those GCG kits only to find out further down the track that the engine is f**ked because it's been running lean.
