Hi all Recently got my car upto full stage 2 spec, so went along to Rtech last Friday for mapping. Nick found my previous stage 1 map was a custom code map which was fuelling lean, from what I can gather he said they adjusted the boost map and nothing else. As it was is was making around 254bhp. Nick worked his magic and after about 12 runs on the RR he ended up in the low 280s... Which is fairly good but it's capable of a bit more. Nick explained that the turbo was having trouble meeting demanded pressure after ruling out leaks he put it down to a weak actuator or the crack in the turbo. On sunday I removed my actuator and it had a decent amount of tension, wasn't much worse than the the I had got which I was told was fairly good.... Replacing it made no difference and after logging it's still not meeting demand up high so I'm putting it down to a weak turbo that has covered almost 110000 miles! So should I send mine away to be rebuilt or buy a new one, iv seen on the xs power site, they are doing them for Â£330, are they any good or poorly built chinese versions? Iv dropped turbo dynamics an email and will give cr turbos a bell later on. I realise I could go hybrid but this would entail a **** load more cost as well as putting the rods in jeopardy, so don't think I'm going to go down that route.
