APR R1 recirc is the daddy. Runs on a diaphragm, fit and forget item and reacts and holds better.
I feel special now....am i the only person running 1 with zero problems lol
Nah, had mine on for 2 years no issues at all. Just needed a bit of playing around with when i first fitted
thats what i like to hear & its even better when on the coldside
i would say you would hear it, though would benefit alot from a stage 1 remap( in more ways than one ) then the d/v sound is greatly increased. well thats what i found with my turbosmart anyway.
ordered a second hand 007p for a good price to see if theres any difference between the two.
