Thats the larger than stock MAF sensor right. I'll take it, I heard that they had some calibration issues with near stock 01-02 LS1s though. I'll look it up tonight and see if I will have issues, if not I'll take it.
JP,
The only time you will run into problem's is after you modify the car BIG time.my car on the 200 wet kit made 603 rwhp and 653 rwt and had a perfect A/F ratio..but anything after that has trouble with tuning..because the tables are harder to tune than a stock maf...this maf is made for closer to stock car's..for instance my buddy with an 02 A4 ss has a lid,cut-out,and free mod's and was running a reg size granatelli maf and swapped to the one I have now the 85mm and picked up 1 1/2 tenths just by swapping to the 85mm. I am building a 422 cid motor very soon for mine so I need a stock maf to be able to tune correctly...anyway's let me know
