I suppose as long as AFR stayed ok you are fine. I would suggest putting a bigger pump in or on there..... 50 psi isn't that bad, hell mine would go from 60 to 30 real fast

Hmm, I didn't know the stock pump had a HP limit. It seems you hear so few people saying that they have replaced it. I guess the Walbro is a good one to replace the stock with?

it would drop to 50 at 5500 and he would tell me to let out so we didn't stay on it to see how much more it would drop....

why am i on a stock pump because i'm not buying it unless i have too... I'm tight with my money lol. I saved for a whole year before i bought the heads and cam I'm not putting anything on plastic. If i can't afford it i'm not buying it lol.
