The "best mapper" question is entirely subjective and premature in any event.
Even the "very best" mapper won't reach 400 bhp from a VF35, the injectors may turn out to be a little short as well. The trick is to have all the right bits fitted to match your brief.
A little word about mapping while we're on the subject. Just because someone can squeeze extra power out of any given situation doesn't make them a good mapper. If they just sit in the car and keep adding boost, ignition whatever until it goes really fast, it doesn't follow that the car is going to last five minutes. A good mapper gets the best out of whatever he's faced with, specification wise, in a way that's sustainable.
In most cases, mappers will do a decent enough job, considering they would usually want to see something else fitted on the car they've just turned up to. I say most, as one or two new ones out there lately really shouldn't..

Nail, Head. Hit!
I would only add to this that you should also find someone who knows what "aftercare" entails!
Find someone who can do all of the above who isn't a million miles away and go with them. I personally use Bob Rawle and went to him initially owning to a combination of reputation and location. I went back each time I got new mods because each time his knowledge and customer service meant I left happy and if I subsequently had any issues, he would always be prepared to offer advice/have a look at the car.

These 'best mapper' threads are a bit pointless really. You're only ever going to suggest the guy you use, if he isn't in reality all that great you won't know because you know no different.
There's a few names mentioned so far that I've heard horror stories about, one in particular mapped a good friends car who had major issue immediately afterwards. However, said mappers obviously have there fans otherwise they wouldn't be in business. And no, I won't be naming them on here or via pm as I have never had dealings with them.
There are many 'good' mappers out there getting good results and im sure you could use any of the above and be happy with the results. I always use Paul from ZEN, his accomplishmemts with his own cars and others are/were enough to make me feel confident in his abilities.

Used bob rawle for years now on all of my scoobs and never had any problems and he has helped me out of so many issues that I'd never use anyone else to be honest

Buy and STi and you've got a better base car... many are running 400bhp on standard internals and you have the calipers to stop you and the gearbox to handle the power! You have to change too many components on a WRX to even equal the STi...
Anyway, mapping wise, I've used
Powerstation (wasn't impressed IMHO),
Simon (JGM) and Martyn Jeffery (EngineTuner) I'd definitely use again...
There are many others as mentioned in the thread...

Mapped my old MY05 STi with a 20g and only ran 340bhp and they said it was max duty on the injectors, it also ran a bit lumpy... decided to get it checked by JGM as Simon was down in Wales anyway and it was mapped to 380/360 and felt smooth and very quick 
Think they could've mapped better but not sure why they never! I had no idea about mapping etc then so thought that was the best it could be...

This is how we see it. BHP is a by product, and shouldn't be your sole focus.
You choose the engine type, turbo, injectors, fuel system, exhaust etc.
You should start tuning by backing off the boost rather than going direct to max boost. You then build up your map on low boost. Then slowly increase it, setting timing and fuelling as you go. Naturally you'll take care of scaling issues as a matter of course, although not everybody knows how to do that!
Eventually, you'll reach a point where you are achieving the kind of power and torque you are seeking, for the minimum amount of boost and timing.
If you are having to exceed anywhere, to achieve a figure you had in mind to start with, you are not in a sustainable position.
That's why we go for tuning principles first, and BHP concerns second.

Sort of.. As anybody tuning Subarus will tell you, the sum of the parts can be very different.

Like I say 400bhp is not set in stone but close would be nice (who doesn't want big boost & horsepower figures),I appreciate its the way its set up that's more important than wanting to have a particular bhp figure.

I ran a 5 speed box with a 2.5 sti block and a vf48 mapped by Duncan graham fantastic mapper and great guy , the box gave way after 5 track days 360/450 as mentioned before good supporting mods and most mappers will get the best all round performance for you and the car.

An observation when it comes to mapper recommendations.
You'll see plenty of examples on the forums of chaps bigging up their mapper like this..
"He's a really nice bloke!" or "He's a really really nice bloke!" or even, "He's a lovely lovely guy and I'd like to bear his child!!" Well, of course he is, he's sat in your car poking away at his laptop and about to relieve you of £100's. He's going to be utterly charming, and agreeing with everything you say isn't he?
Personally, I'd rather a grumpy old Bast--d who knew what he was doing, than a "Sweet young man" who knows F-all....
Luckily enough, I don't do the mapping, as I'm a damn sight grumpier than Martyn, who is neither young, nor sweet..
