After failing horribly, i had my mrev+ professionally installed at a shop and when i turned on the engine, I knew that there was something different in the engine, i could smell the power, but when i drove it, i was terribly dissappointed. I can not feel ANY power. My brother even asked if i even put the mrev+ kit on! I dont know what could have gone wrong. I purchased a copper iso thermal mrev + kit, and i know people are feeling a LOT of gain. I am dissappointed and very jealous. How come people can feel the power and i cant?

 

maybe you're expecting too much..?

 

drive it around like this for a few weeks.. when you have some time.. give me a PM and i'll reinstall your OEM manifold and take off the spacer.. then you'll notice the difference

 

maybe poeple are expecting gains like a turbo or somthing lol not sure. but ive heard nothing but amazing things about the Mrev. 22whp is nice

 

I installed the MD 1/2" spacer last sunday. I didn't notice anything at first but maybe around Tuesday night the car felt very different. Like it just came alive all of a sudden. I think the computer needs to adapt to the extra air or something. Someone told me I should've reset the computer but I was also told by someone else that if you drive it around hard a few times the computer will adapt to your driving style. If that makes any sense. Now I can get 2nd gear chirps in my 5AT that's with the VDC on! I couldn't do that before.

 

Is there data comparing back to back quarter mile times/trap speeds or 30-50 mph and 50-70 mph runs on the same car with and without the MREV within a few hours of installation? I'm curious if there is real world independently measured acceleration improvements. I've seen what the dyno can show but what does the stopwatch show?

maybe its how you drive your car...

 

I agree. After you troll around this board for a while I can easily see how expectations could be higher than reality. You have to keep the increase in perspective of the $ and effort. It is a high 'value' mod. There are 'noticable' gains, especially in the higher rpms. (but it's not a turbo)

 

I honestly don't really feel the gains from the MREV that much, but a couple runs on a Mustang Dyno before and after shows that it made gains... both torque and horsepower went up considerably, and my car is also running richer too.

I dyno'd before, after, with just a spacer, and also with just the MREV plus lower plenum. They all made consistant gains and losses in different areas, but the biggest power gains all around were made with the MREV plus... with just the lower plenum, I think the car lost some power. With just the spacer, I think it was like a 5hp gain almost all around, something like 3hp on top, while making the car run richer, reaching higher RPMs much faster... while the MREV plus altogether made about 12hp throughout the mid, 25lbs of torque in the same RPMs, but nothing on top... maybe lost like 1hp.

Don't remember exactly, but I can always pull out the numbers if I must...

The Mustang Dyno doesn't lie, but your butt-dyno can...

 

Did you reset your ECU??

 

you should feel more "oommph" off of the line. plus, try goosing it at about 4500 rpm. There is normally a big torque gain at that rpm.

I found my g much more fun to drive with the Mrev manifold.

 

How Do u reset the ecu?

 

^^^Do a search for it. It's a pedal reset. You use your gas pedal in a series of steps to reset the ecu. I think I typed in ecu reset to find the thread that tells you how to do it.

 

im installing my 5/16 spacer this weekend. I was told to reset the ecu after. Thats what im gonna do. Hopefully I can feel a difference
