Would like to run a higher octane fuel in my .1TT It has an Evomsit 580/600 tune if I recall correctly. Tubi Race Exhaust. What the popular choice? Thanks

 

Was thinking of the same. I just need a clutch that will hold first. Was going to do the 100 though.

 

MS109 is good.

 

I also run and purchase MS109 from VP Fuels.

103 or 109 should do the trick ....

 

I was going to try this with my GIAC race gas tune. Is your timing advanced to take advantage of the race gas? Any idea how much? I ran 110 unleaded with my GIAC tune and the car is a monster, I love it. I'm thinking about trying MS109 next. Cheers!

 

make sure you try and find a unleaded fuel..Cause lead will hurt the o2 sensors and we all know the 997 relys on o2s to run well

i run sunoco 260 gt plus its comparable to ms109 and less expensive..

 

I typically recommend Sunoco 100, Sunoco GT Plus (104 octane), or VP MS109. I usually stay away from VP100 since it is basically just pump gas with toluene in it.

 

I agree with above, I order barrels of MS109 from VP Fuels, but normally run Sunoco 260 GT Plus when I am pumping it at the track.

SUNOCO 260 GT Plus is 5€ per liter in my country
