Which chip ?

[turbofrank]

Sent my Extender back for reprogramming. I have reds 93&100 chip which
one should i use for a blast.

The 93 will offer less timing and should offer less fueling. Both will compliment alky. The 100 will be more aggressive timing wise, the fueling may be questionable since its designed to run a little higher boost.

I'd use the 93 until the extender makes its way back home

Can always drop the 100 in.. your knock guage and O2's will tell the story.
