HELP! Severe acceleration lag

DIGItonium

I don't have the tuner license, and I can't quite justify $700 for a tuning session at the moment (60k on the motor). That doesn't include the mini road trip to a shop in TX either.

The brake switch issue definitely resolved the power cut issues I had when the car was bone stock. The car literally stalled under 2k for a couple of seconds while making a left turn! I've even floored it in 1st and 2nd while making the turn. There were issues where I could feel power cutting at each 1k intervals to redline, and the tech thought it was fuel cut. The engine is fine, but the throttle wouldn't open up. Once I had the issue remedied, the car sounded different. The motor sounded different, and it hauled angrily to redline and even spun the tires.

Right now it's just the tune under 3k RPM that's a bit sluggish, but I guess it's keeping my rods from snapping. Basically the throttle response is not 1:1 or is limited under 2k or so. The 350Z never had this problem, and it felt great. It might require more skill on the foot, but I rather deal with that than a lazy response.

How many miles do you have now? Have you taken a look at the throttle bodies? That's what I plan to do sometime in August whenever I have time to work on the car.
