I'm new to this site and to tuning, and hope someone can help me out by answering some questions. I have a mostly stock 2007 MS6. Only upgrade so far is a cat back REMUS exhaust. I have ordered a new DP with hiflo cat and plan to get an inlet pipe and a better TMIC, while keeping the original Air Box and filter to keep turbo and BOV sounds down.
I would like to get better drivability and response for daily use. I do not plan to drag race, do track days or any thing of that kind.
It appears that some people have descovered that they have a defective turbo when swapping DP. I am a little worried about installing a DP, on the other hand there is no point riding around with a defective turbo.
I see that swapping out a smoking stock turbo with a GT28/GT30 is proposed as an option to hassling with dealers about warrwanty issues. An other option (cheaper?) is to rebuild the stock K04 turbo.
-Will a rebuilt K04 solve the smoking problem (for "ever")?
-How does a rebuilt K04 compare to a GT28? (in terms of spool up, drivability and power vs. price)
-Does a rebuilt K04 or GT28 work well with the stock ECU and stock boost level? (in terms of reliabilty and gain)
-What can I expect with the above mentioned mods (DP with hiflo cat, new TMIC, new inlet with original air box and rebuilt K04/GT28 in terms of response, torque and hp?
-Which TMIC is recommended? (I see they range from $500-1200...)
-Should I consider lowering the boost level to ensure reliability and how is that done?
-Are there other mods I should consider, keeping in mind that response, drivabilty and reliability are most important, not peak power?
