Sorry for the length of time it's taken me to update this.
So I have finally got the audi sorted. Went down to see phil @ TRP performance in Walsall to get the car remapped. After speaking to rick at r-tech that's who he recom6mended me to go to after informing me they no longer do the 1.8ts anymore.
So after quite an awful drive down from Inverness taking 13 hours because of accidents, roadworks and someone trying to jump off a bridge onto the m6. Finally made it.
So everything started well all pre checks passed. Put car on the rollers to run it up found the lambda sensor was knackered and plugged in the wrong part of the exhaust Phil couldn't read any fuel tables. Anyway new lambda ordered, fitted and working. Success. Although they were a bit concerned about a slight oil drip coming out the exhaust and the car smoking a wee bit on start up. Which I think is caused by worn stem seals as once the car was running there's no smoke.
But anyway back on the rollers to run the car up couldn't get the car to run stable my air-fuel ratio on idle from previous map was sitting at 17:1 but that was before the lambda sensor was fitted. Bare in mind I have covers 600 miles now since then.
Peak boost was hitting 1.8 bar. So much to their amazement the car even made it down without something going seriously wrong.
But anyway Phil scrubbed the ecu and mapped it from scratch.
What a difference in the car. They previous mapper made a complete mess of mapping the car. They had a huge flat spot at around 2500rpm and the mess they made of the pop and bang according to Phil was outrageous.
Phil fixed everything wrong with the running of the car and needless to say I am absolutely delighted with the car and their level of service and would thoroughly recommend them.
Here's the final print out and the final run on the dyno. Sounds so much better now and runs a dream. The increase in torque is amazing for overtaking.
