After the first spike i went back to my tuner and after some mucking around he was certain the problem was fixed but a few hours later i noticed problem wasn't fixed  . My tuner has no idea what it is yet.
Any ideas or any1 else had the same issue with the 06-07?

Are you getting a CEL?Sounds like it is just hitting the boost/fuel cut.You tuner could just raise that limit alittle or try tunning boost for 4/5th gear instead of 3rd.
