OK i know most of you will say wait to get a tuner or use a electronic boost controller but i had a manual boost controller laying around from an srt-4 i never bought and i just got my 08 ss/tc and was anxious so i threw it on. Anyway i only turned it up slightly from stock. It is currently at about 21-22 psi max. My question is it spikes to 21-22 then goes back down to 16-17 very quickly. Is this because the wastegate won't hold? I figured as much but was just wondering why it won't hold 21-22 psi all the way through redline. Anyway thank you in advance.

 

first, welcome


second, you should have read up here first....


ill let others, more inclined to explain

 

Computer is pulling it back.

 

that was an in depth explanation...lol...jk...but true.

 

Ahah that makes sense. Well thank you very much.

 

Nobody says get a electric boost controller for the SS/TC.The manual and electronic will work the same.To raise the boost you have to get a tune.

 

ok i think i will save up for the Hahn PPC tuner. I have been eyeing it for a few weeks and it sounds like a good deal. I was also looking at the HP tuners one but the Hahn seems more for beginners which is definitely what I am.

 

can u send pics of where u hooked up the boost controller i might look into that. im really interested in trying something like that

 

OK sure man but i will have to wait til tomorrow since it's like midnight. It was actually pretty difficult to set up cuz the vacuum line i tapped into is underneath the turbo which is behind the engine so i had to hook it up from underneath then i ran the vacuum lines all the way to the front of the airbox but for sure i will put up pics tomorrow.
