LS7 MAF swap BIGGGGGG improvement!!!!
 

WOW is all I can say.... Im quite blown away at just how much faster my L92 EPS cam swap is with the LS7 MAF card swap on a true 4" intake pipe. I was previously running the stock L92 MAF through 4" pipe and a big cone K&N. I did this as I was sorting out the tune for the VVT and whatnot I didnt want to complicate things by doing too many mods at once. So Ive been bombing around in the thing for about a month now and have it running sweet but today i did the MAF swap and holy moly..... no dyno results yet im just toying around my shop by it feels like a completely different machine now its so much faster up top.

Long story short for any of you cam'd L92/LY6 guys I HIGHLY recomend a 4" intake and the LS7 MAF card swap.

Heres the PN's for anyone interested plus pricing from GMpartsdirect

Bung: PN 19166574 and it runs $9.27
LS7 MAF PN: 15865791 and its $55.52

Nice!!!!

Whats different between the two MAFs?

The stock L92 MAF looks just like most MAF's it comes in a plastic housing that you clamp into the intake somewhere and its 3.5" and has a rather big bulge in the middle where the sensors are etc. The LS7 MAF uses a bung that you weld into the pipe itself so there is no actual MAF housing anymore and the MAF is just a card thats ultra thin ( about 1/4" ) that slides into said bung. Plus it has a fast thermistor as well to adjust IAT's more accurately. My engine LOVED this mod wow I cant stress this enough especially after 5000 RPM it just FLIEEEEEEEEEEEEEEEES now hehe.

Wonder if it would help my little 5.3L?

Its a cheap mod and certainly wont make it slower.... You just have to re scale the MAF tables and your set

What calibration data did you use for it?

pics please

yeah wonder f this will help my ly2 4.8 if so ill do it. can truck drive without remapping hte tables? or does it need to be tuned?

in for pics
