Just put together a fresh A6 Block with Pm-7 slugs, and Z6 Head, got it to idle right but it breaks up around 4-5K like its cutting fuel and has no power!

 

What ecu are you using? Any codes or cel's? Are the sparkplugs, distributor cap, rotor, and plug wires in good condition?

 

well at first it was throwing Code 5-Map sensor and idling like crap, then I realized my friend didnt hook up the vaccum line to the MAP, solving the idling problem right away and now no codes, running a stock si ECU chipped for header, intake but everything is in great condition

 

what si ecu r u running....pm6 si.....or p28?...because around 4-5k on the z6 is where the cam profile is very mild as that is when the v-tec is supposed to kick in

 

pm6, and vtec is not wired yet, do you think that the motor is choking b/c vtec cant engage

 

i would hook up the vtec and not rev high at all until everything is wired. then try it out. keep us posted, i am very curious if this solves it

 

Yeah this is my first time doing this setup, hopefully I can get it running right, should be strong
