Stienbauer and AC shnitzer
Well I'm looking to get some views on the 2 tuning options from Stienbauer and AC.
Both use, from what I can tell, pulse duration modifiers piggybacking the stock ECU, they are claiming 60bhp increase with no DP or intercooler.
AC is expensive at around £2500 but has a warranty of 2 years
Stienbauer is cheaper at around £1200 and only warranty the unit
I used the Stienbauer in the past on a mini jcw and it was fantastic, dynoed at 250whp - with excellent afr- and was switchable on/off, and With it off it showed 218bhp on the Dyno, so it works Just wonder about the m2 and the ability to take a n extra 60bhp
I also like the fact you could remove and dealer wouldn't be able to tell it was installed.
Any thoughts welcome
