Does anyone know how to identify what is on a chip? One came with my truck, but there is no info with it. Not even sure it works, as it was dangling below the dash when I got it.
It appears to be a TS Performance chip, but there are no markings.
Old TS Performance 6-position. Anybody's guess as to what tuning is on it.
Yes, WHS.
A number of different people write tunes for that hardware. No way to really tell unless you can contact the person who bought it and ask what they had done. You can also just get it reburnt with whatever you want on it, if the chip is still good.
Like Justin said, figure out who's tunes you want and send it in for a re-burn. That typically costs less than buying a new chip as you already have the hardware.
