I have WRX with a VF34 turbo with most of the upgrades, and was looking to get a boost controller. What would be some good suggestions be, as to which hold boost better, or which ones will be good at high RPM's?

 

whats your budget? greddy, hks, apex'i? greddy is good for the price. hks is really nice and has a lot of features, but its expensive. same with the apex'i, but its nice. you can program it to have different boost levels at different rpms. ie:10psi @4k and 16psi @ 6k. its really about how much you wanna spend, and what features your looking for. easiest and cheapest route is a manual boost controler.

 

any price, well thanks for the info

 

then its really about how much control you want over the turbo and what features you want. i like the Apex'i and Blitz cause you can control the boost at different rpms and gears. problem is theyre about 450+. i have a few friends with the Blitz and theyre really happy with it. they also make like a g-tech thing that matchs it. give you hp numbers, 1/4 time, 60ft, etc.
