Some of you may know I had my AMD remap removed due to teething problems( putting it nicely)
So I gave the job to R-tech and here are the results
This car is bonkers

"Well all finished now, remapped and full courtesy valet.. :grin Sad to let this one go back to its owner.
A bit of a task this Mk5 GTi with S3 turbo/injectors and HPFP.
The hard part was getting the fuel constant via the air flow correct so the fuel trims are within reason,and the injectors not dumping fuel as the turbo is spooling. Step1 re-scale injectors on a stock map and set the rail pressure maps to work with the HPFP, this took around days of trial and error testing and logging. Next step was to tame the boost and make sure I had full control, the first thing I noticed with running the k04 on the k03 mapping was that under load at higher rpms the boost would creep off the scale, I would ask for around 2250mb, the ecu would ask for the correct load and boost but becuase of the k03 n75 mapping being on a lower scale the n75 realted maps would allow too much duty cycle. So it was another 2 days getting the boost correct and with in maps sensor range and having the n75 act for the k04, it got the the point that the actual boost was running 200mb below the requested line... at this point I had safe control so time to wind the n75 up in increments to give a little spool up over boost which just clipped the 2580mb map sensor and fall back to the requested boost 2400-2300mb. Next task was timing nice and easy to get a base point as the S3 timing maps and scales fitted in place nice.. now just a matter of keep adding the timing in until the ecu started to pull back on the correction of the car stopped making any more power.
I have really enjoyed doing this job as I was taking a lot on doing it, but knew with enough time I could get it bang on. I had no aim of chasing peak numbers, just a car that pulled and pulled like a bitach to the red line.
The final result was 335bhp 310lbft @270.25gs..... £80 woth of fuel used on the dyno and road. "
Would recommend r-tech to anyone! fantastic service
