RichieH 0 Posted November 27, 2016 Report Share Posted November 27, 2016 Hey guys, I will be turboing my mk4 r32 and I was curious what size maf sensor you guys are running and where I can get one. I will be using 630cc Injectors! I'm pretty new to all of this so any help would be very much appreciated! Thanks! Link to post Share on other sites
RBPE 198 Posted November 28, 2016 Report Share Posted November 28, 2016 Virtually all of the pro turbo tunes use an underscaled maf map to handle the boost so will depend on the tune, stock maf can see 450hp+ so no need to upgrade until you reach these limit's logging the data. 630's can have linearisation problems over time, you're better off with Bosch EV's though but again, depends on the tune and how they've been set up or if you buy a generic one or get a custom tune.

RichieH 0 Posted November 28, 2016 Author Report Share Posted November 28, 2016 The tune shop I'm going to recommend I get the 630 injectors since I will be pushing a little over 450. But your saying I won't need to upgrade the maf? Link to post Share on other sites
RBPE 198 Posted December 5, 2016 Report Share Posted December 5, 2016 (edited) The tuner you're using should go through all of this for you, no-one else, as it can depend on how it is being tuned, how good they are, whether or not they are using someone else's file which will need their specific products used. If they are using a promaf tune for example, then it'll have to use that unless changed, same with the injectors. The main re-seller file I have seen is set up for about 470hp using stock maf though fyi. Edited December 10, 2016 by RBPE VR6 Supercharged 1 Link to post Share on other sites
