MREV2 with 5/16 spacer installed with Dyno
What do you guys suggest I buy for my '03.5 AT coupe? Just the MREV2? Or should I get the 5/16" spacer with it?
Some people are saying that the 03's already have a spacer... is this true? (sorry for the newbish questions, but I'm just trying to make the right decision)

If your "non REVUP" engine is already lean (or near lean), this is correct.
If your A/F is good to start with, then you don't need a tune and it won't run lean.

What about just running the mrev2 and not the spacer on a rev-up engine? I'm thinking of just adding the lower collector and not the spacer to maintain stealth especially at the dealership. I mean essentially the mrev is just a machined 287hp lower collector so you can't tell the difference between having that installed or the stock collector physically

There are some very small detail differences that I can see, but I also know exactly what to look for.
Unless you really know what to look for it will never be noticed.

if you get both you will definitely need a tune
then again, you should get a tune no matter what..to optimize your gains..but with the mrev2/spacer combo youll run lean. if you get one or the other by itself youll be fine.
