So far with the "ugly octopus" with two small Garrett T2's and a fixed .48 bar boost we're seeing a best 0-60 of 5.49 seconds measured with a G-Tech three axis accelerometer.
This was in a 90 degree f / high humidity ambient environment.

Cooler weather should bring the 0-60 time down a few tenths....
Will track the car soon to complete the tune.

If you can bolt on and go fast, along with building a reliable motor then why not ?

Yes it works with K-jet but far away from the Standalone system.
My first turbokit I had I used K-jet too and if I boost more then 0,5 then I blowned all vacum hoses and it was leaking everywhere under the octopus. And my gas account was just rising everyday.

If you some day try standalone system you never want to go back to K-jet.

When I opened the engine I could see many spike mark on the pistons and the head only after 0,5bar.

With standalone system I boost 1,7bar with 85 the whole last season and 1,4 bar with gas on stock engine. 1 year later I opened the engine and I could not find a mark of spiking and the engine looked like a new.

This season I boost 2bar and even I blown head gasket and was driving 1 week with water in the engine when I opened the engine the pistons and the head stil looked like new. Only crank bearings was damaged becaurse of water and 1 bearing came loose.

I got much lower gas account too. I consumed more gas with K-jet without turbo then I consumed with standalone system with turbo.

I ispected my car and exhaust gas last week without Kat:

CO: 0,01
HC: 22
Lambda: 1,3

I can say that the standaalone magament system is the best think you can ever to for your car even if you dont have a turbo.

You get more Hp even without turbo and lower gas account

Mercedes engines is very good but with standalone system they are the best

But of caurse everythink about how much the poeple want to pay. Megasquirt is very cheap in USA and works very well and can give you a possibility to boost much more so why not. You dont need to boost 2bar like I did but you can boost 1-1,2 bar and be safe.

But I understand that everybody can not install those kind of things and they choose bolt on kit for 0,5bar and I am agree with that
