bosch 4.3 or 4.4

[Bens850r]

Hello all, been doing the stage 0 stuff as well as other maintenance and have been researching a tune for my 855r. Seems like I dont need the added capacity of the 4.4. IPD id out of my price range as well. I do not trust ARD and I have heard that the Speedtuning ecm runs rich. I plan on keeping the stock turbo and have a modified exhaust. your thoughts please.

What's up Ben.

Have you looked at Vast Tuning? Aaron from VT seems to be the go to guy for our P80 cars.

Thanks for the reply. I did contact him but all his tunes are 4.4 and I need a laptop and cable to datalog I believe. Seems complex and beyond just a step up from stock. But I have heard nothing but good things about his tuning.

So get the euro R tune with no over boost limit from Vast

There's a new tuner sweeping Volvospeed, Calvin from Sovvagn Motorwerke. Basically the same type of tuning from Vast but he has allegedly less experience that Aaron at Vast (?). I'd be interested in a 'scientific' comparison between the two options, but when the time comes I'll probably go with Vast.

looks like Aaron's stock euro tune will be what I will be getting as an Christmas present to myself...haha... I drive the car normally 95% of the time.. and will report back on the overall experience when I get it...stay tuned...

He just finished tuning my car. (16T, green injectors, Do88 intercooler, RIP kit) Aaron is very knowledgeable and provided quality customer service when I was having problems getting my car to connect with the laptop. His tune has been top notch so far.

Thanks for the reply. I guess I will get the ecu this coming week. One day a set up like yours is what I am thinking. Suspension will be after the ecu and it will honestly be a long while before I can do those performance upgrades.
