Goin over 150 shot you might want to start thinkin bout rods and pistons.

I was planning on pulling off some other mods to put me at exactly 450whp on the bottle which seems to be the limit, I figure that since nitrous is going to be less stress on the engine than FI it should hold up pretty well

Now my next question is, if I go with the gt40 pump, what kind of tuning is involved?

im running a 150 shot now and thats kind of pushing it, on just moter the car has 313hp & 325 tq so i think a 175 might be over kill in my situation, anyway im using the stock fuel pump with a KB boost a pump w/stock injectors iv run close to 30 bottles thru the car and no problems at all, i always check my gauges to make sure the a/f is good and fuel pressure is where it should be. but if you do go with the gt40 pump your just gonna have to retune the computer for more fuel pressure
