Does a boost controller add to gearbox wear?

Best thing would be to keep it stock and get your enjoyment from the extra power over your tractor, when you start getting bored then add bits on. As I remember you'll be doing a fair few miles in it so bear that in mind.

Lots and lots of miles :(

Just as an idea:

Work and back 5 times a week - 100 miles
Off to see mates in Liverpool at least twice a week after work - 100 miles
Days off driving, again to Liverpool probably - say 100 miles but variable

Ouch :(

I guess this is all very similar to my Fiat Coupe.

I had a PRV fitted which gave full boost at much lower revs than the standard controller.

That's surprising since the standard electronic boost controller does the exact same thing as a pressure relief valve type manual controller, i.e. removes all pressure from the wastegate actuator until the required boost pressure has been reached. Having tried both back to back on my car, there was literally no difference in boost threshold, and the rate of increase in boost past this was very simmilar. The only significant change was the PRV prevents the huge overboost spikes that the EBV can give.

I would have thought the most pressure was on the gearbox in the higher gears. Or is that just the clutch.

The weakness in the PG1 boxes are the diff bearings, and more torque is available in lower gears. That said, you can rarely build full boost in 1st gear anyway, and it's over so quickly it's hardly worth trying.

I never appreciated the T series on account of fuel useage, but a review on that showed me it really isn't that bad.

I think you are in for a big shock!

Oh bummer. :p

And with regards to the boost controller, apparently the T series uses modulated boost to achieve a nice, smooth power curve and better fuel economy, rather than shoving full boost in as soon as it can.

I looked at it another way - I could have gone out, spent 4 or 5k on a car that's just as quick, instead I've just chosen to spend the extra money on fuel to run this one :p

Can build full boost on a T25 pretty easily!

Provided your front tyres are good and its dry, I wouldnt be adverse to giving it some beans in first gear now and again, but avoid spinning the wheels.

And not everyone wants to race you from the lights ;)

The T series is ok on fuel. It'll do 35mpg pretty easily on the motorway and about 20 when going for a blast.

Mine did 25 everywhere no matter what!

At least it was predictable! :D

Imagine it will be quite a good car to commute in, comfy, fairly fast and reliable, only downside is its not amazing on fuel but meh.

True, the downside being that they run out of puff pretty quickly. A friend had a mildly modified 620ti (decat system and PRV) and the difference in power delivery between that and the fiat was like night and day. The 620 is far more civilised; nice low boost threshold, very linear power delivery but is gasping for breath long before the redline. The Coupe does nothing much until 2500 RPM and all hell breaks loose and it pulls hard all the way to the rev limiter.
