I can’t help but feel that there is more to give from my engine. So I decided to have a look around for some bigger injectors
The 034 kits started coming with Bosch 0280155831 brown/orange injectors. I’ve managed to find out a few things about these
Again they are Volvo injectors, fitted to 5 and 6 cylinder turbocharged engines. 320cc They are a newer version of 0280155759 fitter to earlier Volvo turbos. They are the same flow rate but have a twin cone spray pattern. The 759s spray a single cone. I would think the twin cone was developed for better performance in multi valve heads, though the Volvo’s in question were always multi valve! (I guess Bosch hadn’t developed them yet)
The ones I have now 0280155832s Will more than likely be for sale if anyone is interested! They’re 250cc, dual cone
The 831s are readily available. I’ve just bought some 2nd hand for £40 on eBay I’ll get injectortune to service them. I’m going back to aldon next month, so it’ll be interesting to see what a difference it makes

Hi, been reading your thread with interest as I am looking at replacing my injectors as well overt the next few months. The Bosch 0280155831 look the best bet so I will be going for these, but I cant work out, did you mod the resistor pack like the 034 kit ? or did you leave the resistor pack as OE and Audi built it from factory ?
Thanks for the write up on this, been real helpful, just the resistor pack issue now to sort out.
Cheers
David
