I switched my dump valve back to the recirc from a atmospheric turbo smart. Since i have changed it, it seems like all the power comes in at 3.8-4k. It still spools in the lower revs but it just seems all the power comes in around those revs any ideas?

 

Sorry it's an 05 STI.

 

You definitely hooked everything back up ok?

 

I think I did, when I done it i double checked that it was all on properly. I will do it again tomorrow as it is raining at the moment.
