I just installed the engine, it is a low compression 427
the build has a GT9 cam,GMPP LSX heads and 1700cc injectors (going twin turbo after the break-in)
The issue im currently having is I have a flat spot off idle. if i roll on the throttle it's ok, if i hit it i have a flat spot.
Any input would be great, also can someone confirm I scaled the injectors correctly.
