Corvette Magazine Article LS1 2/07
In this highly regarded magazine the author states that the push rods on the factory LS1 are soft and need to be replaced with another specified brand, a new cam and lifters, all the standard stuff until the statement: "by reducing the air fuel mixture 5% they got an additional increase of 10-12 horsepower at the rear wheels!" The article claims 60HP increase overall at the rear wheels in the article, worth a read and comment.
I have reduced the air fuel mixture by 2% and thus far see no real concerns as the air fuel ratio is currently 14.5 to 1. Is 14.25 better? Don't want to stray too far before I start burning valves!
Help.

I assume they are talking about PE (WOT) mode. In closed loop mode it will seek ~14.7. If you get PE to ~13 you will have the desired result, forget the delta%.

Air Fuel Mixture
The WOT on the car was showing 14.85 with the peformance tune using the Diablo Predator sport, tunning down to 13.5 which will be about 8% or 3 beyond where the max allows.
Anyplace on So. Cal where this show car, actually a daily pampered daily driver can be taken to get the optimum performance, price is no object if the work is superior.
Thanks guys for replying, knew I had a problem with knocking at idle use chevron 91 premium, spark floats all over the place using diagnostics, need a pro to tune this beast.
