Haven't seen much in the way of turbo upgrades available let alone a dyno graph of one, thought i'd share the find. Cant find any reference to the turbo replacement (or impeller upgrade (like weistec offer)) on the mcchip-dkr website though.

 

How much is the power after the tune?

 

King Monkey on here has/had upgraded turbos. He ran into a lot of fuel issues. Look up his posts.

Should had a V8

 

This is why. That' s 332,000 of your US dollars for a 63 in the OP country. The 43 is $153,000 as it is

 

I thought about doing the turbo upgrade from Renntech for my 20 GLC63. Decided against it, I don't keep cars very long before I get bored. I got their tune, it makes the car quicker. Definitely not some crazy difference.

 

That's impressive, making those numbers without a meth kit.

 

Weistec w3 turbo upgrade, methanol/ water injection 75% Meth, ECU and TCU tune, blow off valves, high flow air filters cat delete.
