1.a. Fuel. Make sure you fill up with the best fuel you can get, this will vary from state to state. Here in California we reccomend using 76. It has a higher octane than all others (some people even claim thier 91 is actually 92) and it doesn't have the MTBE additives like most other companies. we have seen the best results with it, heres some *proof*
Cheveron Vs 76
1.b. If you plan on doing a race gas map along with a 91 octane map, come with very little 91 octane in your tank. Bring with it a gallon or so of 91 incase you run out while tuning the 91 map.
2. Your car. Make sure all lines, fluids, filters, EVERYTHING, is in order. Trust me, you don't want to find out that your car has a boost leak that will take an hour or so to fix while it is on the dyno, and believe me... we see this happen all the time
3. Dyno Sheets. If you want your dyno sheets please bring a blank floppy disk so we can save your dyno runs to it. We no longer print out dyno sheets, we seem to go through printers every week
4. Your mods. Make sure you go over your mods with us over the phone before you go to get tuned. We might give you some suggestions, or ask you to bring stock parts if we feel that the setup might have some problems. This is only precautionary to make sure everything goes smoothly.
Call us if you have any questions
