hey guys, i need y'all help. okay so let me start that i have a 2010 evo x mr and been driving with full bolt ons and pro tune. so recently i decided to upgrade my intake cause i had a POS cobb SF intake (not dissing on cobb or anything, i love those them and there products) to a MAPERFORMANCE 3.5 short ram intake. i hooked everything backed up and i noticed that my car was idling a little funny and when driving around it bogs like BAD. so i thought maybe that i had a vacuum leak, i checked and rechecked EVERY vacuum line that i touched and everything was on right. so then maybe i thought that my MAF sensor was dirty so i cleaned up that bad boy and had the same problem but now I'm pulling up a P0113 code.

so my guess is that maybe since the SF intake was smaller then the current one. maybe thats why? i just need to reassure myself since yall are experts

also i'll (try lol) attach a datalog that i did on my way back home from work. THANKS GUYS FOR THE ADVANCE

The weatherproofing on connector for the MAF can make it a tight fit. Try disconnecting and reconnecting it.

Does the problem clear up if you throw the old intake back on? Simple test, no?

Since the intake is bigger you are in need of some MAF scaling tuning to compensate for more HZ air flow?

Hit up your tuner tell him you changed intake and might need maf tuning.
