i read somewhere that pre-95ish W140 engines had more power than post 95ish engines - due to the ecu throwing loads of fuel in at full throttle - this has been disabled in the later cars for emissions reasons

does anyone know if its possible to fool a post 95 ecu into thinking its pre 95?

1992 was the last year for WOT(wide open throttle enrichment)! HP went down by 5-6% on the same cars in 1993 & later.
Emissions & CAFE(mileage) were the factors in that change.

I believe it's a chip change.

If you're interested I'll sell you a 1992 M119 5.0L chip. Please Private Email me.

You are correct, you should not use a 5.0L chip in 4.0L M119.
