Ok so yesterday i finally installed all of my mods on my g35 and i barely seen any difference, or not any difference at all, lol

I have an 06 G35 4 door, 6 speed

i installed

MREV2
5/16 Basic Spacer
6 wire grounding wires
Stillen cold air box intake
Megan resonated Test Pipes


I dont know why is it slow, i thought the mrev2 would give me power that i would notice right away,

is it maybe because i installed the test pipes and the rest of the exhaust is stock?

Also i have a small air leak between test pipe and y pipe,
Could that be a problem?

Thanks, a lot everyone, any info would help.

thanks, Paul

 

yes thats a problem lol, did you reset your ecu as well???

 

yeah i reseted the ECU couple times already, could a air leak be this bad effective though?

 

haha well i certainly wouldnt leave it like that....

 

I didn't know MREV and 5/16 spacer can be put together?

 

haha yea....its supposed to have the most gains for the rev-up engines...

k ill fix that, and i will put on my aftermarket y pipe and a mid pipe, maybe that will halp,

 

is that my old y pipe you still got over there?

 

Did you use the new gaskets for the test pipe to y connection? What makes you think you have an exhaust leak?

 

I'll bet it's the test pipes. You are losing Back pressure that gave you more torque down low. You are most likely makeing more HP on the top end (above 6000) but the low end grunt is down and that's what you feel the most.

 

lol, yeah i still have it lying around, but your old G is sold for like 7 months already, some asian guy bought it from san francisco.

 

i used my stock ones, well i could hear it make some little wistling noise when i let go of gas.

i will change the gaskets also, thanks, for informing me with that.

 

do you have stock exhaust on yours? and where did you feel the power gain when you installed your mrev2?

 

Right now I have a NISMO R tune Cold Air intake, an MREV2 and an HKS rear section muffler.

The MREV made the biggest difference, woke up the motor from 3500 to Redline.
