Hi again its me fas, i have have installed a free flow cat converter, my car is giving flames from the exhaust when i rev it or **** gear at 8000rpm, i would like to know is it natural for it to do soo or am i runnin lean, the other thing is i want to install a a/f ratio monitor so should i attache that to the stock O2 sensor of the car or should i install a seperate O2 sensor as i have one from venom, please advise. your advise would be greatly appreciated......

Without proper metering, it's a guess but im gonna say your lean.

Get an a/f asap. Dont you have a fuel controler?

Your going to need an ECU or reprogrammed ecu very soon if not now.

you can also slap your car on the dyno. they have widebands too just to make sure. rotaries backfire.... that is normal

whats the cheapest anyone has gotten a 5 wire FJO wideband 02 kit for?

i think you get them for like $350-400 or something.
