Dyno results
Had my car on the dyno on Saturday. Here are the results. Power is about where I expected, but it looks like I am running pretty lean. Car is an 01 225QR. Mods are GIAC X, NGKBPR7E gapped to .028", VTDA, MBC, Forge007 yellow spring. The first run was 21psi. I saw that it was lean so we did the second pull at 18psi. The power dropped, but A/F stayed exactly the same. Third run was the same as second. What could be causing this?I assume those bumps on the graphs are timing being pulled.

RE: Dyno results
Having a cat and the a/f being read from the exhaust tip. This causes it to read lean by ~1 full point. Also the stock tuning already runs lean. So if this is what you have and how it was tested, you are fine/normal

It is at peak psi and my best guess would bt the n249 opening the dv a little bit. Dont think timing would of been the cause unless you had severe pull which is less likely. Your psi didnt fluctuate at all did it?
