2009 L76 Spark Table and TPS question

[HL04SS]

Does anyone have good spark table (or a good baseline spark table) for an 09 L76? Preferably for 87 octane. Also when logging a WOT the scanner only shows around 83% on the TPS, is this normal or is there a problem? When I purchased the truck the previous owner said he had warranty work done twice on the "Gas Pedal"

Thanks in advance for any help!!
