Hey guys im planing to buy a fuel regulator (you know the one youti intall in the fuel rail) for 40$ . do you think is worth the 40 buck for the performance i will get in my 95 ex . If yes how much PSI you guys recomend to set it?

 

I don't think its worth it on a stock car. Increasing the fuel pressure on a stock engine will not make any HP. You pumping more fuel into your cylinders but you have the same amount of air entering the engine so you really will just be running your enging rich which doesn't really give you any HP. FPR aren't a good mod for a stock engine.

 

i do have cold air and performance muffler. hey i was wondering noe taht you mentiones how do you call when you fuel-air ratio has execs of fuel and how do you call it when you have exess of air?? is there any autometer to know this ratio??

 

Honesetly, your best to save your money for awhile untill you can afford a swap or a diffrent car. Now, that was the voice of reason but when it comes to fuel regulators you can get a small gain but only if you are seeing a major change in performance that is causeing a shift in your A/F ratio.
