I'm going to politely disagree. I'll bet that most of the power increase can be had with just a good 93 octane tune on a Gladiator. From what I've seen with GM LS engines, unless you have ridiculously high static compression (13:1 for example), there's not much to be had going flex fuel naturally aspirated. Now, add forced induction, it's a totally different story. An extra 50 to 75 hp on a 650 hp engine is easily done.True, but you can still get a bunch from a na engine with proper tuning.
We were getting 550 out of 2liters with only 13.5lbs of boost on E85, but I totally believe Livernoise about their claim of +50hp.
