Re: N/A 74mm Throttle Body Upgrade Guide
What sensor are you referring to when you say "old sensor"? I know Needswings sells the larger MAF housing and upgraded MAF sensor but I figured with that upgrade, the original wouldn't be reused. I also think it's possible that the 74 mm TB I ordered could've been damaged because I talked to a gentleman who performed the same upgrade without the accompanying MAF sensor and housing upgrades. To answer your question, a Vietnam Veteran had it in PA, but he couldn't drive stick for many years because of Agent Orange. It sat in his garage until he decided to put it on Facebook. I got it with 15.5k on the clock, I've put over 2k miles on it, and I intend on driving it until it is no longer able. That is, unless the right offer is made...

Admittedly it has worked for some who drove the car for a long time before the computer settled things down but others never could get that set up to work.
But if you do the math on the airflow you will find the smaller MAF sensor matches the engine better.

Would the 74mm throttle body and MAF from the S500 work for this? Found one on marketplace and I want to try this. I could also have the wrong car, as some people told me it was the CL500, not the S500
