Ok so I have been spraying 175 through a direct port setup for a long time. I decided to up the jets to a 200 and there comes the problem. I hit the nitrous right off the t brake and it pulls hard until 7000 where it sputters like a rev limit. I made sure the msd 6010 rev limitissethigher. If i do a pull on motor i can go to 7500 no problem. Thisissue just started as i increased the jets. I have an aeromotive pump feeding the regulator set flowing at 5.5psi. I am lost....pleasehelp guys!! Ok so I have been spraying 175 through a direct port setup for a long time. I decided to up the jets to a 200 and there comes the problem.

What do your plugs look like? What fuel? What does your timing look like?

Agreed, colder plug needed.

I am running 110 fuel and 18 degrees total timing. I do have br8es plugs which are one step colder I can try. Do I not have enough timing?

Sounds like your runing out of fuel or something with the plugs. Did you put a new set up plugs in and try spraying it? Can you log it or get it on a dyno?
