Message That seems like a lot for the type of fuel and boost . My JWT records 16 degrees of timing at WOT using the Techdom. I am only running 18 psi of boost. My MAS voltage was 3.92 volts. 33 degrees is double the timing . Did you happend to compare the timing curve of the JWT program? According to JWT the timing I am reading is normal. I thought + 5 degrees advance is the upper limit on race fuel. I think the stock ecu has the timing limit at 23 degrees? The reason people can't run stock ecu is because the timing is too advanced for pump gas. The JWT ecu ups the fuel maps and reduces the timing. My egts hit 900c of because the timing is conservative.

I know every car is different, but double the timing is a huge variation.
