Problem Roush 427IR on the way to Roush

[vector1]

your v/e table looks pretty messed up from 3400+.

the a/f base map is pretty rich also and the spark advance is pretty conservative at the lower rpm and cruising.

look at the 427 chevy sb 48# injector prom ram 544 hp setup for comparison if you want something close.

if you're datalogging you should be able to come up with a better v/e table and smooth it.

i think i would find somebody else to tune it or do some learning.

when your v/e table jumps around like in your table from 3400+ i don't think it is going to run well. it needs to be smooth.
