Re: Valve pinging upon hard acceleration? (TBM-Engine & Drivetrain)
well i had a 2004 trd ac that pinged all the time except when i ran premium
or tanked up here in canada(usually buy my gas in the u.s.) but my 2005 sr5 dc has never pinged until i made some recent mods (read sig) now i hear i slight ping when shifting and under light throttle. anyway the other day i was looking thru the owners manual and on the back cover noticed that it said for increased performance 91 octane feul should be used so its off to the us tonight to tank up and pick up my nitrous kit but that another story
