Hi SFO
Sure you can BUT....tuning the plus4 will never make it similar to the 3L (3.7L) V6.
I had my plus4 up to 195 bhp and it is TOTALLY different from the mkIII Roaster I have now. Personally I enjoy the Roadster much much more. A matter of personal preference I guess. If someone is at that decision point, the best advice is go for LONG test drives in both cars and go into red mist mode and lazy cruising mode in both. Remember a tuned plus4 feels like a normal plus4 below 4500rpm (but noisier).
don't disagree .. but the Roadster is £10,100 more than a +4 ...
You can never have too much power, but there is something quite enjoyable about wringing a +4 at high revs if it has been 'fettled'
