Show me a single scroll over 400 on a stock 2.0 which isnt laggy,
Is it a daily car ?? No !
Do I care ? No !
Am I happy ? Hell yea
Your great at making snide remarks but have not says anything that even shows a hint of knowledge ?
I have asked you to share what you think is the correct way of modding ?

Im comparing to 335bhp on my stock turbo so of course it will be more laggy.

Difference between lag and boost threshold
I think there's a lot of confusion on what the term "lag" actually means.
It is my understanding that "boost threshold" is the RPM at which the turbo will be capable of building full boost.
For example, if you put your car in 3rd gear, at 2000 RPM, and you hold the brake to prevent acceleration, and floor it, the turbo will not spool up to full boost.
If you do the same thing at 3000 RPM, the turbo will build full boost.
"Lag" is the time it takes the turbocharger to spool to full boost, once past the boost threshold.
Example, you're in 2nd gear spinning at 5000 RPM with your foot off the throttle. You suddenly go full throttle, and there is a lag time before the turbo gets to full boost, despite being past the boost threshold. This is what I see "lag" as being.

Lag to me is the period between 0 boost and full boost... getting full boost as early as possible is important

I agree with you on that yea.
Just that most folk would call a car with a higher boost threshold. Laggy although they would be incorrect.
If we are being scientific.
My sc42 now has a higher boost threshold than my vf35. But is less laggy due to being a ball bearing turbo.

I'm feeling philosophical.
It's like the human body. We all know that smoking, drinking, eating crap and not doing any exercise is bad and long term will lead to an early death. However, we've all heard of the 100 year old who smokes and drinks rum every day. We've also heard of teetotal professional athletes who die of a heart attack at 28.
So as it is with cars. Sometimes you get lucky and find car that will stand up to huge amounts of abuse and neglect and still never miss a beat. Sometimes you get cars that get treated amazingly well and still die at 60,000 miles (I'm still bitter). However most cars will live a bit longer if you don't abuse them and treat them properly.
Until they go bang it's hard to know what you've got.
