Flex fuel is the easiest mod to install that I’ve done on my car. KingLT1 tuned it and took car of the tune part. It literally could not be any easier. I spent just a few minutes installing a Bluetooth adapter (Fuel It) on my fuel line and now I can read ethanol content right on my cell phone after I fill the car. So I always know exactly what my ethanol content is. I’ve been using ethanol blend and making about 100 additional whp for several years now and I’ve not had one single issue.

“I don't feel comfortable pushing the envelope on 93 octane ever. I've never been able to get over 700 with just 93 octane on an LT” “I don't know what stock is, but if it were me I would try to stay close to that. Anywhere between 600 and 700 is as much as 93 octane can handle” And this was after I told him I was doing the aux pump as well on 93, what do you guys think? As far as gauges go, someone previously said using the Bluetooth app that can be connected to my DSX flex fuel sensor will be great to see the e content cause I can just go on my phone while filling up and see live what happening. I was initially looking at getting the AEM gauge to see AFR levels but there’s so many that I’m not sure which one to get that will suit my concerns the best. There’s so many different fuel pressures to look at I’m not sure which guage could accommodate that. Should I just get the AEM guage and just look at AFR or should I get a different one that can show me more of the different fuel pressures? |

The fact that he doesn't know this is worrisome as a tuner, unless something was lost in his statements. I've seen up to of 875whp on 93 octane on an LT4 and that is pushing it. I've seen 850whp done quite safely on 93 octane. |

I don't know where you read this, but I disagree with this. A bone stock LT4 car, even with a low side, trying to run E80 will tank the fuel pressure and run out of spray window. Maybe if you're at 10,000 feet of elevation you can.

It was a video made by LMR and he says they just had a low side with a flex system that could do either full e85 or 93. Maybe he meant to say blend because I was also surprised you could do full e on just a low side

I believe that was with a cam with a 38% fuel lobe

So can you do full E with Cam and lowside ? probably less than stock boost level tho?

A bone stock LT4 with stock fuel system will tolerate about E70. With a low side upgrade, you can do bolt-ons(Headers, CAI, TB), X port, and run E50-60 depending on DA. If you add a cam with a 38% lobe that extends fuel headroom up another 80-100whp. 760-780whp on E50-60. To go further then you need to upgrade HPFP and Injectors or Go Port Injection. The only way you might get away with Full pump E(E75-80) on stock high side, is if you did a 38% Cam, headers, cai, lowside, and run stock boost with no supercharger porting.
