Through a collaborative effort of your friendly 6.5 staff a rather descriptive synopsis of how the 6.5 turbo system works can be found in the FAQ sticky, which takes you here

Go through it before giving up all hope, I doubt your turbo problem is as difficult as you imagine, but to fix it you have to do you homework assignments presented above.
Guys/gals I know us mods sound like broken records on the use of the FAQ, but they are there for your benefit there is a lot of great info within them, site veterans please direct the new members there first before jumping up and answering the questions, if you know the material exists but can't remember where PM one of the mods we will be more than willing to help you find it.
Yes FAQs are not ideal and need some tweaking we realize that, point it out in PM to us what changes for the better you desire, if we don't get back to you it is not an implication your idea is a bad one, we may just have not gottin to it, or have gotten overcome by life's everday progress and have forgotten it. If you don't hear from us ask again, also use the multi address feature put all mods on copy, one of us should get back to you, we converse behind scenes often enough one of us will clue in the other one, that somebody here has a question.
There are a lot of members here now to keep happy, so we will have to temper what we do as something that benefits the whole, that said don't say how dumb an idea is as happened last week with a request to consider the sticky name change.
Obviously consensus was a no change vote, fine which is why I asked on behalf of a few others, but I was somewhat disappointed at the blood lust & frenzy that came about with a simple question; and how dumb the idea was we are better than that. Forum will only improve if we don't stiffle enthusiasm to make changes, there may be a good reason to not change we can share that reason without attacking the idea or person/s asking it.
