I have a 03/2003 Corvette cpe 6spd, LS1, 3.45 axle, with a Vararam VB2 CAI - 160degree Hyperstat, 40,000 miles, everyday driver, 12 miles to work, I live in Atl,Ga (hot & humid during spring &summer) no other mods, all else is stock.
I have the DiabloSport Predator U7198 programmer.
I need to know what specs to start with, I ve got most alll the pinging out by adjusting the timing to 1%+ in the mid & upper rpm settings.
I am experimenting with the injector curve at 1-3% + range.
she seems to run fine but what else can I do
before this the car seemed starved for fuel at about 4500 rpm under quick accelleration.

Follow the sticky above to get the LTFTs dialed in and you should be all set.
I am lost as to how you got rid of the pinging by adding timing? That seems backwards to me....
Thanks
