Having been brought up with "Old Skool" tuning with carbs, cams, aftermarket ignition systems and the likes; this mapping lark is a bit of a black art. Anyhow I've had the car two years, an 04 WRX wagon, and following changes to the exhaust, a set of wheels, bigger antiroll bar, a new set of front calipers and a set of Hel hoses it was time for some tweeks. Aiming for a PPP equivalent the required parts were fitted and then it was off to Edinburgh to get the map sorted out.

After much thought I spoke to Alistair AKA Trackhound Tuning and arranged the time. That was a couple of weekends back but I didn't do the usual drive back post as I wanted to give it time to get used t it, and I have been well impressed with the results.

I've had some bad experiences over the last few years with various garages and have lost my faith in the services they provide but that faith has been restored slightly by the way that Alistair has done his buisness. The discussions on what I wanted were factual and in no way misleading with no huge claims of what could be achieved, questions during the process were answered without leaving you wondering about his abilities and best of all he took the time to follow up a few days later to see that all was well after the run back up to Aberdeen all of which is rare in itself.

Would I use Alistair again? Certainly.

Is mapping still a black art? More a shade of gray now but I'm still not trying it.

No power figures as it was mapped on the road but it was planned to be around the 265 / 270 mark which Alistair reckons it is now but to be honest I wasn't chasing numbers just drivability.

I'm well impressed with how it is going now, it's a daily driver so the right foot has to be a little lighter but getting used to it. Getting a bit of torque steer when pulling away quickly but a play with tyre pressures should hopefully sort that out and if not a change of tyre brand when needed.

Fuel ecconomy is as expected as it's around the same as it was before the wor nder normal circumstances but give it stick and the feul gauge drops quick :) .

The PPP route was chosen to give an increase but allow for improvement once I get bored with how it goes now. The only nightmare was getting the third cat out as there had been a bodge job on the flange between the downpipe and the cat and the gearbox mount had to be removed from the box to get bolt out. The intercooler hoses were not as easy as I expected but that was due to the dump valve to inlet pipe hose clip being in the worst position possible and my lack of foresight to get bigger hose clips. I'm now of the opinion that the real PPP pack is not as much of a rip off as it originally seems, apart from the generic map, as in total I spent around a £1000 so adding labour onto that would probably have taken it to the £1500 of the PPP. Using open source for the mapping took a lot of thought and was chosen for for reasons I'm not discussing for fear of starting another drawn out discussion but the difference in price does make it very attractive.

It's getting a health check on Saturday which again speaks volumes for the man's operating practice so we'll see how it is then.

The only dowside of the trip down was that I managed to drive from Aberdeen to Lanark then to Edinburgh and back up to Aberdeen and only spotted one other scoob, totally different from up here where I normall see at least a dozen a day :) .

All the best,

Steve
