I just put in a turbonetics manual boost controller. When at high boost (ie 18 PSI), the engine feels like if cuts out. Not severe but it kind of feels like it is stumbling. I have a greddy BCC set at 4.29v and a fields harness. Could it be I am hitting boost cut or maybe I need to gap the plugs? any sugestions?

Thanks

Could be boost cut but I am not sure what mods do you have are you running stock plugs if so you might wanna consider iridium's.

you most likely need bigger injecters if you don't have them already. when you push that much boost you hit point in the high rpm's that is called "fuel cut out". this means your pushing so much air that your injecters can't push that much fuel to get the right air to fuel ratio
