Firehawk ???

Have anyone looked at the Firehawk tune and shifttables? Are they different then stock Trans Am?

They're the same as regular F-Bodies (well as the ones that came w/3.23 rear gear.. the 2.73 rear gear cars are obviously different)

OK... I read somewhere that the Firehawk shifted had a different shift-tune. I must have been fooled.

A friend has a 94 with a Firehawk shift-table he says. But thats a LT1...

The 94 and 95 LT1 cars had an option for the "Transmission Perform" button. Some cars got it others didn't but all cars had the capability. It required jumping 2 wires on the PCM I believe and it would improve shift firmness and more aggressive downshifts
