i have an 05 6mt

here are the flowing mods i have in order that i installed them

1-hyper grounding kit
2-z-tube
3-crawford plenum
4-megan y-pipe

now the problem....

i seem to have lost power, i haven't dyno-ed my car yet, but, it just feels a little slower on the low end.

did i go wrong somewhere? or am i missing a mod that will put everything together?

any advice will be greatly appreciated

 

I dynoed a big fat "Zero" with a 1/2" plenum spacer on the 05 6MT. Others have reported they lost power with a plenum spacer on the Revup motor.

Try switching back to your stock plenum and see what you get.

 

The Plenum is a mistake on the '05 engine....they redesigned the plenum on it and the factory/stock plenum is superior to anything aftermarket. Take it off and try to sell it to someone with the older 03/04 engine.

 

thanks for the info.

one more question...
do the spacers and carwford plenums help after you supercharge the 05 engine?
