Hello. Currently running an NX 150 shot through a nozzle. Since the car came back from the dyno it does not spray in 1st or 2nd gear only 3-4. I'm using a NOS brand window switch. Could a setting on the window switch be the problem?

Next question revolves around my power level and fuel upgrades. I have comp cams stage 2's ready to go in along with a FRPP manifold. Should I step down to a 100 shot with those extra modifications? Or should I keep the 150 and upgrade my pump? I have a low mile motor but I don't want to get greedy and blow the thing a part.

Thanks for the input.
