[QUOTE="q6543, post: 16826534, member: 163900"] Right, 1st you need to verify that 30* out of boost is safe max timing for your car on 93. Then the generic rule of thumb is pull 1* per lb, you may end up re scaling and interpolating, or not. Every 7 kpa over 100 is 1 lb 135 kpa =5lbs 170 kpa =10lbs 205 kpa =15 lbs. So if your 93 out of boost 100kpa was 30* I'm at 28* but apples to oranges. Then you would pull timing linearly so your total would add to 30* ie at 205kpa 15* This is also why E85 is awesome, I run full timing through the first 5lbs of boost and then only pull .7-.8/lb .....19-20* timing @ 19-20lbs of boost. Hopefully there is something helpful in my explanation, and more people chime in. [/QUOTE]
