Volkswagen Golf R32 MK5 gains 34 lb.ft torque and 39.5bhp with JBS/Custom Code and Milltek exhaust

I'm thinking of taking the plunge. So far I have read many good things about this tune and vvt tuning in general. I have some pretty long winded explanations that I could post here but it may be a boring read. In short the oem vvt is tuned for fuel consumption and emissions purposes along with catering for every type of fuel and lack of maintenance, with power and torque last on the list. We know this kind mentality to be true from the detuned OZ version of the R golf. The JBS tune adjusts the exhaust and intake cams timing which in turn changes the airflow, cylinder filling, compression pressure (not the same as combustion pressure) and then adjust the fuel and ignition to suit those changes. The result is a significant torque boost from low revs all the way up to redline. A few guys in the UK on r32oc forum have reported strong boosts in the low to mid rev range from this tune.
It particularly works well with the Miltek as the change in exhaust flow and subsequent decrease in back pressure can cause loss of low down torque with an increase in upper kw’s (I found this with the custom exhaust on my 3rb but that’s another story) but the VVT attack tune adjusts the cam timing and other parameters to ensure that this low down torque is increased instead.
The more I read, the more I like.
