Going racing this weekend and since Ive switched to E85 my turbo isnt spooling up as quick as it did on race fuel. I need to build a lot more exhaust heat. I have a the dynojet ignition modual. What rpm ranges should I have the timing set at? 6000-8500 31*???

With ethanol you will need a few more degrees then stock, but also with ethanol, you wont get the same high exhaust temperature as gas............:)

Yah on race fuel I could pull 8psi in nuetral for the launch, now on E85 its about 5psi. From what I have read I need to add more timing in the low end with more fuel. Im pry gonna shoot for 11.5: 1 A/F on my gas guage from low to mid rpm, then pry 12.5:1 on the top end. Just need to know what degree of timing I need to be at
