Engine load is often above 90% or even maxed-out in that region.
Rica's E-power upgrade claims 41 Nm (16%) more torque at only 15 rpm more than now, and a 15 HP increase @ 4000 rpm.
According to their published claims, top end power is higher than stock, no need to make sacrifices there even though we'd seldom go there
Use RICA Engineering - Performance and Economy Tuning for Volvo, BMW, Audi, VW, Mercedes and most other makes and models to select your car.
Price info is in the text on the left of the power curves.
Price : €580.00 EUR + VAT (€435.00 EUR + VAT for cars over 3 years old)
Looks like they only have a power upgrade for your Svietlana though.
The E-power upgrade on my car is €363.75 EUR + VAT as it is over 3 years old - so with VAT (state tax in the US) it's still under 450 euro (and more) I got quoted for the tinted windows  |
Are you sure the engines are exactly the same ?
OEM generally will try its best to met high MPG, not sure how much they would lean out and any ignition advance would probably mean higher octane .
Now, if like above poster you want to lower the sweet spot of power band you could say use a camshaft with less duration and lift . That and slight tuning if necessary should help .
I haven;t checked in long time but many camshaft makers had eco/low rpm efficiency profiles available .
Edit : I was referring to you post on DrivE-models .
