52mm throttle question
If I replace my stock 48mm throttle body with a 52mm will I also have to adjust the MAF tables? I think I will but the reason for asking is I got the 52mm in the mail today and if I do not have to change any tables I will install it now so I can run it at the track tonight otherwise I'll wait untill next week.

Will a 52 mm TB have a change on the MAF tables? Probably, but not great would be my guess.
Best way to determine the effect of a 52 mm TB would be to properly tune the MAF car scalar tables with the 48 mm TB using a Wide Band O2, and then install the 52 and determine if there are any differences.
Unfortunately, I don't recall anyone on the DIY Prom actually testing this and posting any results. So go for it and let us know.
