If you go to corvetteforum.com in the n2o/fi section and do search or just ask on new thread: What HP will stock fuel system support? The F-body guys usually change out their pumps, but C5/Z06 can handle quite a bit more hp before swap out is needed. Stock pump on both of my vettes, no problems.

Pumps vary from car to car. My stock pump would only support 100 hp N2O. Thats on an 02 Vette. Definitely change your plugs before spraying any more. Also get it on a wide band dyno and check the A/F. Thats the only way to really know what your car is doing. BTW my car now has a Racetronix 255 pump and booster pump. No more fuel worries here.

well i think im gonna go with the walbro 255 intake and gap my t6's to 38 or 40. but i ended up going to the track and just using the 75 shot and well i really think the next thing i do to the nitrous system is gonna be drag tires 
i went way sideways when i hit 2nd gear at the track but i had bad traction problems in second when the n2o kicks in my best on the 75 shot was a 13.4 @ 110 so i need some tracion and i'll be in the low 12's for sure
