I have been searching on here after reading there are RB maps. Is this true? I have only found it mentioned once.

For the RB guys what tunes do you run. I hope to have my RB's on in the next 2 weeks and have a Cobb. Should I be buying a Pro2.5 for $450? I do not plan on ever running meth.

you wont get much out from Rbs without running high octane. Yes there are upgraded turbos maps. Mail Cobb when you have the turbos in.

When you say run higher octane, are you talking like highest available pump gas (93/E85 blends) or 100 octane/race gas?

both and you need meth injection.
Cobb has an MT rb car so no issues for the maps.

youre upgrading your turbos bc you want more power, but youre refusing to run methanol still? get over it already. it will make any turbo'd car run stronger, and allow more boost without the DME cutting it and adjusting timing. just run methanol!

[ChuckD05]

Agree. Not sure why there is a small percentage of people who all refuse to run meth.

Esp with rbs

I am upgrading turbos to get ride of my waste gate rattle in both and howling out of one. I found a used set of RB's for what I consider a reasonable price. I am not upgrading for power purposes only. I would like to stay with a flash tune only and thus meth is not going to work. I am sorry my choices do not make you happy.

WHO KNOWS. I will have methanol on any turbo'd car i own from this point on.

Meth works GREAT with flash tunes. Just saying.

Are you saying you only want an OTS tune? Why not get a Pro tune on your AP? I don't see a map that's one of the Cobb OTS versions that is designed specifically to take advantage of those turbos. I imagine Cobb may have some maps, but not sure they're giving them away as OTS options.

Either way, once you've spent this much, what's a few hundred dollars more to get a safe, accurate custom tune on your AP?

contact cobb or dzenno on b.immer.b.oost to get you started.

For one, Meth isn't easily available in my country. Secondly I worry too much about the system failing, leaking etc. I don't want to wonder all the time if the meth injection is really working 100%, checking for clogged lines etc etc. Too much hassle involved even though the power gains are nice, obviously.

You're not alone. I tried meth and couldn't get it working right. I'd rather see more effort being made for pump gas.

My RB's will go in the car next week, and I don't plan on running meth. I always run high pump octane anyway (RON99-102).

Also my primary reason for going RB is (horrible) wastegate rattle and generally worn turbos. The extra performance is just an extra bonus.

you can just run a 1/4 tank E85 and run slightly more aggressive map

Same here.

Although I do have a methanol system, but it is a huge hassle as there are no competent shops here that can set it up properly, and then there is one more tank and more gauges to pay attention to. Also, the risk of the meth system failing when I'm doing 300 km/h is nothing I really want to think about.

The power gains with the RB turbos on pump gas alone are quite nice already and can easily be felt as compared to the stock turbos at the same boost.

I've been running a beta map from COBB for a while now, but am not satisfied with it - boost oscillations, laggy throttle response, acceleration continues when going off the throttle etc. Which is why I'll be trying out other options in the next few weeks, i.e. the JB4 G5 board and an upgraded PROcede.

That's exactly what my plan is

JB4 G5 is all you need with cobb. Also Jb4 is good for power on WOT but on Track Cobb is way superior. Just give it some time , cobb is working on fixing the oscillations and with ATR there are more possibilities now.

Good to hear about the performance increase even without meth.

I also do long drives in and through Germany and I've actually done 302.8 km/h (Vbox verified) and have the same concerns you do.

I will run my RB's on the JB4 initially and hope to get a G5 board soon.

My stock turbos run just fine on map7 with Aral 102 ultimate, so it'll be interesting to see how much boost the RB's will be able to run on the same fuel.

With the new E85 (autotuning)maps the future looks interesting, even with out meth.

Well I've had my RB turbos for a few months now, so I think I've waited long enough. In any case there's no harm in trying alternatives I think; I already drove a PROcede tuned RB turbo car and it was much better than with my COBB maps.

I had a track day last week and it was just there that the shortcomings of the COBB tune were most glaring. When I let off the throttle, the car often continued to push, which makes judging entries and exits in corners much more difficult; when going on the throttle again it took too long to build up power to accelerate. Also in part throttle situations the power delivery was inconsistent.

All these are symptoms that I do not want to see on a track and which are problems that I did not have before with the GIAC flash. I'll now try and see how the JB4 and PROcede do, and if they're resolving the above mentioned issues I don't think I'll look back.
