Now that I'm starting to understand more and more about tuning and what some areas of concern are, I have pulled tunes out of both of my cars and compared them to stock tunes just for the heck of it. Both cars were tuned by 2 different shops. I paid top dollar for these tunes at the time and was very understanding when they had the cars for a few days.
My WS6 which is cam only(TR224 112), ls6 intake, all the bolt ons and green tops had only PE adjustments and idle adjustment. The only timing changes were in the idle and low load areas. MAF = stock, No VE adj(I figured with a different cam, intake, and headers the ve would be different), no timing adjustment in the WOT area, and the only change for the injectors was the flow rate. And I wondered why this thing ran better with the lousy custom predator tune it originally had. I figured a dyno tune would be better then a mail order tune not the case here.
The G8 isn't much better. Mods are tvs2300, 1 7/8 lts, rotofab, 160 tstat, ls9 injectors. Set to MAF only(not a biggie but the guy who tuned it told me how much he worked on getting the part throttle af right using efilive; but the ve constants are still the same as stock), really low timing (like 10 degrees at wot), again only change to injector tables was the flow rate, PE set to 10:1, Zero trans tuning(again I was told how long they spent on tuning the trans), pe enable set so low this thing goes into pe at the drop of a hat.
I know its easy to armchair quarterback but shouldnt paying top dollar net top work? Its no surprise that both cars dynoed low for their mods.
I'd like to personally thank everyone on this board who helps guys like me learn to do this the correct way.
