I knew a magnum would be as strong as a stock LS and you pretty much have proven that. So I have thoroughly enjoyed watching this. E85, especially pump E85 varies greatly in octane. Its also only 105 octane (the good stuff from VP) so E85 can be a tuner’s nightmare. You can for sure detonate a turbo motor on E85. Also running the timing so retarded can also be hard on a motor. It wont detonate but it can load up with fuel and hurt rods and pistons. Its better to run more timing with less boost and end up at the same power level. To a certain extent anyways. There will be a sweet spot where it likes to run timing wise and at lower boost which means less heat from the compressor and overall it'll run better. I tune my own Holley EFI on my turbo motor and have been since the 90’s. Just FYI for you, so you don't think I am some internet keyboard warrior lol.
