I can't help but think that modding my car has actually made it slower. Anyone else ever have this feeling before a tune? I know I have read a tune is supposed "wake" the car up, but I don't ever see stellar results (10whp is what I have been seeing as average right?)

As the car sits now it has gen 3 intakes, test pipes and invidia gemini exhaust. On a closed circuit (because I really don't condone street racing) I had a couple races with some friends and one guy with a stock 2008 automatic 350Z and myself ran. We were pretty much dead even until we let off near the end of forth. Same went with some runs with a stage 2 newer style GTI.

Now, I noticed when we were done running it, my oil temps were slighty above 260. The general opinion I get from people on this forum is that it doesn't matter (Although, I would love to see someone log some pulls in their cars at different oil temperatures to prove this theory...but it appears no one has.)

So I ask a few questions:
1. To those of you that got tuned: Was the car considerably slower before getting said tune?
2. Has anyone actually logged their car at different oil temps to verify that ecu does not pull timing or throttle depending on the oil temp/ engine temp?

Now yes, I have been on these forums for a hot minute and I know many will say search this and that. I have looked all over this forum. I promise. If I missed something it would have been by accident, not lack of motivation to find.
