Hay all. As some of you know I'm now running a single turbo set up. After mapping yesterday the car felt amazingly fast when the mapper took me out. And on the drive home, it ran a treat.
But I'm getting the most annoying problem as from last night. I'm getting ridiculous boost spike in low to mid range.
Whether its on the 1.6 bar map or 1.3 bar map the boost shoots up to about 1.9 bar and just coughs and runs pants. In 5th and 6th it all seems to be fine.
I'm running 7psi strings in both wastegates. So that shouldn't be and issue. But its strange how straight after the mapping the car felt great. So it leaves me thinking its a technical issue maybe. I'm about to go check that the wastegate vacuum pipes are ok. Anything else you lot think that might be with checking?
Thanks
Paul
