What would be the best thing to buy to help keep constant boost pressure? AEM Boost controller/gauge, Grimmspeed selenoid, boost pill... I think it's our turbo that causes that(?), but is there any way to help or stop that drop in boost pressure in higher rpms with oem turbo?

FYI I will be getting the AEM boost gauge anyways, even if it does nothing to help. It really looks good.

Thanks.

 

A tune will help you hold higher boost.

 

A tune is good but is there any way to keep that boost all the way through the rpm range?

 

Go for a tune Drop me a mail when you have time and I'll flash your car with GST v2 You'll see the difference. And you should order the boost pill, this will help too...

 

Thanks Buddy Ill call you on the weekend!

 

I noticed a big difference with the GST V2 and boost pill. My car is still 100% stock. My next mod plans are an EVO X BOV, EVO X FMIC with pipes, and then probably an exhaust.

 

to answer the main question rocky, no, on the stock RA turbo, there is nothing we can add to hold our peak pressure through out the power band.

The reason being the turbo is simply too small to flow 22-25 psi constantly through the entire band. It falls off at about 5200 rpm regardless. A tune does take that 9psi at reline stock to something more in the 12-17 range, which is very nice.

 

Thanks guys!
