Just installed 93 oct tune .... Runs Great ,but quite alot of pinging when accelerating hard

Any suggestions ????
Also can you make additional changes under modify after the 93 OCT TUNE has been installed ????

Remove some timing and add some fuel. Give that a shot and see how it responds.

Is this done on the modify tune mode on the hand held unit ????? if so how much timing to remove & how much fuel to add???
I am new @this .. so go simple on me ...Thanks

Yes, use the modify tune. I am going to assume you have a wideband. What do your AFRs look like? I would only change one thing at a time. If your AFRs look good, pull a degree or two of timing. If you are lean, add fuel and see how that goes.
