You can get your 4k springs, "maxxed out star screw", and your 100 fuel plate and gain nothing by these upgrades but some high egts. High egts and black smoke mean nothing, nada, zilch. There is a ton of power to be uncovered without spending a dime on ppump parts. Tune the pump you have now and you'll be surprised what you can have especially since you are trying to save your clutch. Why not spend the money from your injectors, springs, and fuel plate on a clutch first $.02
