As for how many runs you get dean...As many as you can get in line for. I've goten 12-13 passes before...and it beats sac.. 50$ for a 4 hour test and tune..

so running 100 octane doesn't do any good if im using a 91 oct. map? i sure seem to see the difference correct me if im wrong

Only if you'd knock without it. A proper 91 octane tune won't knock under normal circumstances, but even a good tune will knock on a hot day with a heat soaked IC. This is where you'll see the benefit of NOT LOSING performance due to the heatsoak>knock>ECU retarding timing. 100 octane actually has less energy per liter or whatever than 91 octane, but since it does it's job and decreases the propensity for the car to knock, you can run more advanced timing and boost on it. That's how race gas tunes will take advantage of it. I spike my octane with Torco when I autoX on hot days even though I'm tuned for 91.

Yup, that's where I got it from. However, mixing some 100 octane unleaded in is your best bet. My tuner likes Torco, but he says race gas is best if you can get it. We've got that VP in Sparks with 93 and 100 octane at the pump. I'd just try to run a that if you can. It won't store as well as Torco though.

huh yep ive used the vp 100 but wonder how old it is, or how long it sits in that tank since it's so spendy...

cody · 2009-03-26, 01:57 PM

Good question. Wonder if the employees or management would tell you how often they get it filled.

It turns over pretty quickly with all the guys in the Best Buy parking lot buying it!

cody · 2009-03-26, 02:13 PM

Ha! Also, Ed's tuned several big turbo Subarus in the area and they all got race gas tunes. Most of them street race. It probably does turn over fairly quickly, but it's all relative...hopefully it comes in small frequent batches.

shit they probably add a gallon or two of prestone octane booster in some 91 and sell it for 7.65
