thats why is good to test another tune. if it misfires on both than you know for sure you have an hardware issue somewhere. these engines are so freaken sensitive to misfires...

Nice numbers! It seems like alot of people have been moving from other tunes to the G5 lately with great success. I need to upgrade my G4

You absolutely must. The G5 ISO is worlds different even on a stock n54. I just installed this on a buddy auto awd 335i I can't believe it going from the g5 to the g5 ISO is a major difference also.

considering the same switch myself. my car has never really run great on the procede and I'm maxing out fuel trims up and down and it requires a lot of tweaking to get it right it seems...

It's not like there is any sacrifice to make the switch in my eyes, cheaper and more power in most cases also the little things like the steering controls gauge sweep all that jazz.

This is the reason in power difference. It's a very simple explanation.

Customer service is another issue in and of itself.

Is it possible the additional fueling provided by the COBB flash may have resolved some fueling issues that may have caused the misfires?

But then, I don't understand why Vishnu didn't just suggest a Procede flash. Who knows. We're all just speculating.

All that matters is that your car is making insane power now!

Oh so that explains why I won every race against the others 335i running Procede at the track.

And I thought it was because of my driving skills

Without a fueling reflash you will not take advantage of running E85. That is why the jb5 and Cobb flash has so much more power. That also probably accounts for everything else.

If your customer service experience was bad than that is a reason to switch.

Damn. Definitely makes me reconsider, and i totally understand what you mean as far as customer service goes. Not sure if they are too busy, but i would handle the CS differently if i was fortunate enough to be an owner.

No I'm saying these fueling issues were fixed long before I did the Cobb flash. I did that for the 100% e85 And timing advance. I was content with the setup but I was beyond tired of going to 2 gas stations every time I got gas.

I wouldn't go back to the procede if it were free but that's just my 2c!

yup.. its not that hard to put in your mix and if you have any doubts do a log.

Besides doing logs it beneficial to just winging it and letting the vishnu or cobb flash auto tune it. At least you will KNOW everything is in check by logging instead of assuming. Even when i end up doing the cobb flash or if i had the vishnu flex sensor for that matter, i would log log log. I like to listen to my car thats why we get along so well

Second of all I couldn't get my car to run correctly on the Procede and Vishnu kept blaming Injectors, Spark plus etc to why my car wasnt making power.

So here are the dyno runs- E92 335i 6mt

Procede V5 Rev 3, 93oct/e85, 50/50, 3" DP's DCI's and an FMIC the car made 385.11Whp and 412.43Wtq at 53* temps.

JB4 G5 ISO 93/e85 50/50 Mix, 3" DP's DCI's and an FMIC the car made a best of 441.59whp and 483.93wtq this was with the clutch slipping very badly. So the highest full pull I was able to make was 433.59whp and 474.93wtq this was 64* temps.

So I am very happy with this switch and the car is so much faster on the street! I have also added the BMS/Cobb backend flash, 100% E85 and NLS 2 Step it is amazing what this car feels like on a 30* night and full throttle shifting.

I just ordered a clutch and will be hitting the dyno once again. I tried scanning the dyno sheets and can't get them to upload correctly will try again when I get home.
Which map are you running on?
