I'm new the the Lt-1 game and have not had the chance to ever work on my Z. But im having problems in the high rpm range when my foot is against the floor.... When i get into these high rpms my car will drastically slow as if dying on me... please help me out or give me a few more things to work with so i can get this problem fixed! Thanks alot!!

 

Fuel or spark.

Is it sputtering, cutting out, falling on it's face.....a little more detail por favor. Check fuel pressure, check plugs, wires, opti. Completely stock? Feel like valve float?

 

It feels like im completely letting off the gas... she is falling on her face for sure... im talking a drastic loss of power... how would i go about checking the fuel pressure?
