Would adding a plenum spacer change my a/f ratio? I would suppose so, but not sure. Would I even have any real problems with a/f? If so, how would I solve the a/f ratio problem without getting an aftermarket ECU?

thanks

 

Might change a/f alittle, but nothing to be worried about. If I were to do headers or cams I would get a aftermarket ecu/tune for sure.

 

Yes, headers will defiantly change everything.

 

i just put on strup headers and leaned way out.
