I just got the ls1 ups and running in the first gen. Fuel press is good, no mil light. The idle starts high, Drops to about 550. When i hold rpms up, the engine rpms fluctuate. It also has very bad throttle response, engine speed seems to increase only after the low fluctuation in the the idle. Anyone have an ideas, thanks for any info.
