MAP!!!

im beyond playing with stuff like this now. My car is my work horse and as long as it gets me from A to B reliably I don't really care!!

but, out of curiosity, would you know when the turbo is supposed to kick in?  I'm having a serious stutter at about 1,500 rpm sometimes. I can also hear the turbo bearing 'whistling' so am thinking it's on the way out. Hyundai won't change it under warranty as it hasn't 'failed'. I think I'll be going along the 'how long was it being lubricated ( or not) by contaminated oil causing premature wear' route. 

In other news, the oil level in my 3,000 mile old brand new engine is now 5mm above max and my fuel economy has dropped by about 10% again... Must book it in again...

Sounds like diesel is getting in , the diesel will wreck the oils properties . 

As the graph suggests stock  peak torque is near 3K , his previous 2.0 tdi was sub 1800 rpm .

Whilst the remap has improved the low rpm it's not a cure as it's part my father's driving and part the hardware of the car. 

Some cars have amazing flexibility low down torque , the 1.7 i40 doesn't . 

It's a small engine larger turbo arrangement probably to chase favourable CO2 emissions .

1.7 136 and a VAG 2.0 140 , the larger  turbo in the Hyundai  allows for near 2.0 peak figures at the expense of slower spool of the larger turbo  . 

A larger engine smaller turbo is the sweeter drive and this car should of had a 2.0 or twin turbo . 

Triple turbo's will be seen in the near future .
