Renntech Tune - How much boost?




Not sure about RT but other tuners are probably boosting over or at 21psi... depends on how strong the tune (which isnt necesarily better due to engine safety)
This is why Renntech now is going to bigger turbos to increase boost to over 22.

Also - Any idea the % of how much larger the turbos will be?
And my last question is what HP will this get them to?
I'm looking to do this as soon as possible..
. Thanks!

. Thanks!They also expect to drop into 9's with 140mph trap...
I have the car coming in November,hopefully the set up will be ready by then.
So far,did only the ECU in wife's G63 and the difference in acceleration is staggering.




Are you sure about this?












I wouldnt want a hold drilled in mine.
we scan the vehicle before and after the tune. the only fault i have seen is the torque curve which is ignored when they re-program but the sds picks it up.
Now, not saying that it is a perfect world here... I did have an issue with a 2012 s65 going into limp, but tech said it was the tune... turned out after I drove it, made it go into limp, it was a faulty upstream sensor... told him to replace, no problem since.
so I am sure some dealerships will cry "bloody murder" as some techs do... but they are just stuck in the past...
Today is different, people will buy a $200k vehicle and toss another $40k easily at it to make it their creation.
Personally i like RENNtechs tune and after dealing with Brabus and Kleeman... I will only stick with RENNtech, I also believe they will outlast Brabus ... hell I don't even know how Kleeman is holding on
sorry Kleeman, wish it was different
See its all the stuff above that keeps me from getting a tune. Even now it seems there is inconsistency with tuners and their re-tuners as to the specifics of the process.
I'm good. I'll stick with the slow pp e63

The only way the warranty will be voided is if the unit modified caused the damage. just like with anything ... from adding a radar detector to plug in the cigarette lighter GPS units...

So modding an ecu to change engine boost and or timing that leads to engine failure would not be covered? (the Engine) Sounds about right--- the dealer is offering no added warranty here base on the facts presented here.
