Dyno'd today with the Lund E85 tune & JLT Intake

I had an opportunity to dyno the car today here in Houston and it put down 493/411 on the first pull and then backed that up with a 492/410 on the second pull. The air here was not great today - 79% humidity when the runs were made. About 72 degrees.

I have the Lund Flex Fuel tune and a JLT intake. I was running 100% E85.

Overall I've been very happy with the Lund tune - zero issues aside from a little bit of the delayed cold start. Car is running strong. Anxious to see how others are comparing.

Now for the resonator delete...!

What's a delayed scold tart?

Nice one Helmet - you got me man. I meant "cold start" - edited now..!

Nice numbers. Guess it might be worth going out of my way for e85.

Where do they sell it around us?

Great numbers!

Nice #s but baseline?

I'm guessing you didn't do any pulls before the tune and intake. That would be interesting to compare.

Doing before and after with e85 would be nice but something of a PITA given that you have to run your baseline on pump gas, leave to fill up on e85, and then strap the car back onto the dyno, assuming you want to make all runs on the same day to maximize accuracy.

Agreed - I wanted to do a before and after 93 pump vs E85 but logistically didn't have time to pull it off. He'd dyno'd 2 other 350's and both made 445 and 447 bone stock on that dyno. So give or take a few I'd imagine it would've been in that range. I will say that the jump from 93 to E85 was not as significant as the jump was from stock to doing the tune. The tune itself was just on 93 the single biggest improvement - I was surprised actually.

I'm running the 1/2 mile here in Texas this weekend and will get some numbers on how it does in that event.

Well, that tells you pretty much all you need to know. There's no reason to think your baseline would have been any different. Those results are very consistent with what has been published and virtually identical to the JLT Youtube dyno where they got 448 stock and 486 tuned with JLT intake on 93. Add probably another 10hp for e85.

What injectors did you upgrade to for the E85?

Stock Injectors

Hmmm interesting, I know Shaun at AED won't tune e85 without an injector upgrade....I wonder what the duty cycle is with e85 on the stockers at say 500-525 rwhp?
