Thats for your 04, now post up an attachment for a 97-03 GTP.

Not sure on the L32, but it makes sense that you would be able to. The SC/Intake is much more efficient than the L67 (which is 91+ only). The L67 runs a smaller pulley stock with a smaller port between the SC and Intake this equals more heat.

I don't doubt the L32 can take 87 or 89 as the GenV eaton is much more efficient, but I personally still never would in ANY forced induction car.

No way.

Doesn't all the grades of gas come out of the same tank, albeit with different mixtures of octane booster? My guess is the difference between 87 and 93 is that 93 probably gets more ethanol added to it to boost the octane.

no tard. The car he mentioned was an 04 GTP, so I proved that an 04 GTP can run on something other than 91+. the 03 and older do call for 91+, but no one is debating that.

No, the way gas gets its higher octane is that its run through the process one or two more times. I'll have to see if I still have the books from my fuels class.
