Is there any benefit to running a higher octane with the Dinan flash. With my previous tune, I was using 100 octane pretty much all the time (full tanks). Since the parameters are set with the flash (I believe) would I see any performance gain (besides draining the wallet) if I were to continue using 100 Octane?

Thanks in advance

My buddy attorneyscott just filled up with Sunoco 104 oct GTPlus and his butt dyno says it makes more power. He dyno'd it on 104 and got 339rwhp and 370rwtq with Stg. 2 (non-revised) + exhaust. He does not have any baseline on 93. FWIW, our Dinan contacts indicated that the car would in fact produce more power on 100+ oct.

As Sniper already said, Dinan Flashed cars love the good stuff. You will feel the power increase. Great for the track.

All 335i's stock or otherwise, will make more power on higher octane and less on lower.
On a stock car I dyno tested that was on 91 Octane, I got like 4 rwhp more in a matter of minutes of powering in 100 Octane to make a 94 Octane mix.
With appropriate adaptation time, I'm sure even the stock car would of picked up a couple more.

The question is, unless you are racing regularly, do you feel you need to run around with 100 Octane full time?
I know you did it with your PROcede because you put the levels to 100%.
Personally, I'd do a 50/50 mix of 100 and 91 at most for everyday driving, then if headed to a track run that down low ahead of time and go 100% 100 Octane.

I don't see why you'd feel a real need to even put in more than a gallon or two of 100 Octane per fill up for everyday driving, as a tuned 335i is faster than 97-98% of the cars out there even on straight 91 Octane.
To spend $40-50 more per fill up to have an extra 8-10 rwhp in everyday driving is expensive.

But unless you feel you need it since the Dinan tune seems to put out similiar torque to PROcede v1.4x down low in the rpm range, but a decent amount less horsepower than PROcede v2 above 4000 rpm and especially above 6000 rpm.

Save your money, just put in a bit of the good stuff with each fill up to counteract our crappy 91 Octane gas if you feel you need it.

BTW, has anybody made a major claim to Dinan yet?
Since a Dinan tune still voids the BMW powertrain warranty and I've heard Dinan has been shady in the past paying larger warranty claims.
Wonder how they will handle their first ($1000+) warranty claim (or a major $3000+ claim) on a Dinan flashed 335i??

Cool.....thanks

I agree Michael..... I dont plan on always running full tanks as I used to...

thanks guys,

Around here the difference comes to about $20 a fill up, and I really only fill up once a week lately, so I'll probably just keep running 100...

Even though i said it up above that I wont, I'm sure I'll still continue to do so...even if it is only a mental thing. ha ha
