There is a few things you can do.
Do not take out the MAF screen!!
Change plugs to NGK TR55
Use GM topend cleaner to clean off the pistons..
Check PVC system for oil in the intake.
Do those steps and you should be alright.

We'll i'll one up something seems wrong, to I wouldn't drive that **** down the road 10 feet. If it was oscillating like that on the dyno. Thats a REALLY SERIOUS issue if your dyno looks like that. I'd go get my tuner and put a 9mm to his head if my car dyno'ed like that.
Only time that might be acceptable is if i was hitting the limit of the dyno like 1000wft/lbs and the tires were spinning, but that car is SICK.
Keep pounding on it, and wonder why the pistons split in half man.
serious. Go to the dyno archive and look for other dyno's like that you won't find any.

Your problem is not that serious.The things I listed above are simple to do.By the way the graph looks,you should be feeling that while driving.
When's the last time you got a tuneup on your car?How many miles on it?
