This problem started intermittently when I got the car in the fall; it's an 08 xi. I chalked it up to bad gas or high iats initially, but now it happens all the time. The thing takes FOREVER to get to 60, like 6-7 seconds. The engine just sounds loud and wheezy too. The problem is most drastic if I punch it from~20mph in second and take it to redline. I self tuned Saabs for 10years and in looking at the the logs, the only thing of note is that the afr seems lean, around 15, but there is no timing correction that would suggest knocking, and it is pulling throttle to 40%, but maintains torque and boost. Fuel pressure seems normal, too.
Car has supposedly had it's intake walnut blasted, but I haven't been in there to see. Also, wgdc seems very relaxed at 30%.
I have a China charge pipe and VRSF 7" ic.
Thanks in advance,
Cm
