i just installed my zex dry kit im going 4 a tune im useing rc 440 ijectors and walbro 255 fuel pump i was wondering if i can use more than a 75 jet and if i can will th control box still work?

 

no one knows guess ill go with a wet kit i just like the easy setup of a dry kit

 

Yes the control box will still work. I had a dry zex system on my piston rod b16 w/100 shot...... When it came on it was a torque monster On the 100 shot just make sure you retard your timing and a good fuel pressure regulator. I was on 100 shot dry zex, rc310's and a 255hp and it worked out for me
