Gas Smell... do I need to re-tune? When I bought my LS1 the previous owner had it tuned to run rich because he had planed on adding nitrous. You can smell it when it is idling (gas smell). Is this fine, or do I need to get it re-tuned?
Mods are Comp Cam 224/227-.560 i believe, Hooker longtubes, Corsa cat-back, Ported Trottle body, SLP lid.

Its worth checking the tune to see how its setup in any case. Open loop or closed, maf or mafless etc. You can also verify idle, wot and timing etc.
So in summary yes, check the tune, it might be fine, but you wont know unless its checked.

I have seen some rigged tunes before so its worth checking into. I looked at a "nitrous" tune recently and all that was done was about a 10% change to the IFR table
