its confirmed my problem is my feul pump. so which one? theres a walbro on new era performance for 105, its a 255lph. is that to much for my car. Or does it not matter? my stats are --- CAI, !CATS, headers, flowmaster cat back, maf ends, LT4 HOT cam kit w/ 1.6 rr's. those are the only things that would affect the engine anyways. more to come tho.....

There is no problem with installing a bigger pump than you need (as long as you don't get silly
). The fuel pressure regulator will return the unused fuel to the tank. I run Bosch pumps, and each 210LPH pump is good for 500HP. I ran one of these as an inline booster pump, with my stock pump and stock regulator, for many years when it was a bolt-on motor with a 125-shot of dry nitrous. No problems with the stock fuel system.
Just be sure you get a pump that is rated at 43psi.
Racetronix has some nice "kits" that include a larger pump, and upgraded wiring.Fred

I run a Walbro in my GN and am extremely satisfied. Great pumps!
