Before/After 93 to E85 Lund tuning Dyno.

Nice numbers

Just tested my car last week and according to the dyno 93 and e85 overlap each other for my Lund tune and the same for a dyno tune I have. Any reason my car wouldn't pick up anything over 1-5 hp at certain spots? I'll try to get graphs again

What i dont get it is why your torque didnt go up that much. You should be at 380 tq with 93 octane already.

Huh? My torque did go up 14wtq to 380tq now.
If you're at 380tq with 93 you're on a high reading Dyno or using std Dyno numbers.

Pretty close to what I saw. With the addition of long tubes I was @435 on 93 and went to 450 on e85. Torque went from 400 to just 407.

And here is baseline, 93 tune and e85 tune.

Oh I like that... the history of your modifications. Very cool.

No i m not talking about the e 85 portion of it. You said your stock torque was 357 and with 93 octane it only went up to 366! I would question that tune. 9 lbft with a tune seems way too low. Even conservative tunes see gains more than 10 lbft just on 93 octane. On top of it you are running an intake too right? This is also a pp car with 3.73's? You need to send a datalog to lund to review your log. I am 100% sure you will get better results. Normally flex tune pp cars see around 390 lbft running e 85 and 380 lbft running 93 octane. Something doesn't add up with the torque in my opinion!

All dynos read differently. These results are very typical from what I've seen. 3.73's don't affect torque numbers in the slightest. That is gearing, not hp or torque.

I'm quite happy with the tune personally though. Lots of gains through out the rpm range. Lund has these tunes dialed in imo.

The reason i mentioned the 3.73's is because you have a manual tranny with lower drivetrain friction loss compared to auto's so the torque number completely threw me off. I still suggest doing a datalog and sending it to lund. It won't hurt. You get free datalog with a tune anyways. What if they dial you in with an extra 15 lb ft? Wouldn't you like that?

I will be posting my dyno results this Friday. It will be on 93 octane using flex fuel tune and just a drop in filter plus 170 degree thermostat. Now i m curious to see the stock vs the tune.

Put my car back on the Dyno yesterday morning after loading the Lund Flex fuel e85 tune.

Previous Dyno shows the 93 Lund tune.

Was super humid yesterday and a lot hotter but still picked up over 10whp and 14tq. Only mods are Corsa Touring axle back, JLT Intake and sct Lund tuning.

My baseline Dyno was 378whp. All same Dyno. All SAE corrected.

Nice numbers. I am thinking off going this route but adding the PMAS intake as well. So I am guessing about another 10whp on top of your 415whp from what I gather that people are seeing. That should equate to a ballpark figure around 425 whp, which would be nice little jump from stock and worth the investment.

Good stuff though and thanks for sharing your info.

A friend of mine who has the Lund Flexfuel tune with Steeda CAI, Mach Thunder catback and running e85 put down 418/387 SAE on a 96 degree here in the Atlanta area. He had 4-5 revisions done on his tune, too.

My car with the same exact mods but tuned locally by Injected Engineering put down 423/391 SAE. My car is only pulling 26-27 degrees of total timing, too. Not sure what Lund does for total timing. Our cars were dynoed back to back, each with 3 pulls.

Both cars are manuals, too.

Been trying to decide on the 93 vs e85 but these numbers pretty much have me sold on the e85. I have seen some people say you need injectors and others say there is no need, anyone know which is correct?

LT Headers, no cats, H pipe with magnaflows, JLT intake and a Lund 93 tune.

I'm looking to go E85 after I install the paxton this weekend!

You do not need injectors for just intake/tune with e85.
