Thanks for the comments. I knew that the DP would be a blanket recommendation, but it does sound like there could be some reason to believe this is plugged, especially if my description is what Amp is referring to as "hesitation". Ultimately, I plan to have all the bolt-on items, along with a PFC and wideband O2 meter, but I don't plan to do any serious modification for about 6 months. At the moment, the car is project #2, and I need to be spending my time and money on project #1, which is a turbo 13B powered experimental aircraft (RV-3). I'll consider going ahead and getting an M2 DP with a second bung for the sideband O2 on the way. That should provide a nice delay https://www.nopistons.com/forums/pub...DIR#>/wink.png



Amp, I am really interested to know if my problem (make that my car's problem) is what you would describe as hesitation.



And one more thing. I just noticed that my post level is listed as FNG. Hilarious! https://www.nopistons.com/forums/pub...IR#>/boink.gif



Thanks,
