if i built my block do u think it will be fine on the stock ecu until go back on boost?

 

depends on how wild you went with the build...if you stayed close to stock compression, stock cams, stock valves, then there should be no reason you cant run off the ecu.

Im not gonna run with managment for the first 1k miles or so (not reinstalling turbo till iv gotten things somewhat broken in)

 

I did it for the first 2k miles. When i built my motor and no boost i was running no managment. So long as your build doesnt consist of aggressive cams you shouldnt have a problem.

 

just built bottom with arp head strups car runs fine on the ecu slow but fine lol. just thought i would ask
