I have been told that you can run a one step larger fuel Jet then instructed to do so on the little chart that comes with my TNT F2 Kit, just to be on the safe side. Is this true and will help the car from running to lean, or will this mess the plugs up from to much fuel being delivered to them.

 

I had to use a much larger jet than recommended to get a good A/F ratio. I suggest spending $100-$150 on dyno time to be certain you are running a safe ratio. Everyone's setup is different.

 

Air fuel is something you should not guess with. I would suggest having the air fuel checked.
