    Just curious if anyone has seen a dyno above 399whp for the cst4 on e30 or anything higher than 358whp on 93 pump. I have ready it should be good for 430whp. I just havent seen anything near that. Thanks.

    Not without auxiliary fuel whether it be meth injection, 6th port or port injection.

    You'll be out of DI injector headroom in the 380-400whp range

    I made 375/375 on e30 with stock motor. I did not have any more fuel headroom to push it safely.
