Always running 87 but think i'm filling up with 93 now that I got my UPS email today. Cant wait, been going crazy waiting for the tuner. 2" AS, new stereo (amp, subs etc.), new exhaust,cold air intake and linex all in the first 2 months...just hit 2000 miles on my 06 Screw. Xcal2 is the final piece.

 

I think that you're going to be VERY pleased with the final piece of your puzzle... best of luck!

how long you wait... i was thinking about putting in an order

 

6 week wait but, I bought it at the end of the group buy. Same time they were changing shops though, sure it would be a little quicker now. By no means am I complaining. So I dont start a new thread, my fuel light just came on. Anyone know how much further should I need to drive to empty out the 87 octane to fill up with 93? or should I just fill up with 93 now? Does it matter if there's a little 87 in the tank?

 

I talked to Mike about this and he said you can fill with 93 octane when the fuel light comes on then download the high octane tune. You probably have about 4 gallons of fuel left but you don't want to run out of fuel.

Exactly, very well said - as soon as the low fuel light comes on, you can go ahead and fill up with the higher octane fuel, and then go ahead and install the higher octane tuning, and you should be good to go!
