I have a 93 400E and I have always been disappointed with how underpowered the car feels. I put a chip in it, but that didn't do much, so I went back to stock.

My 92 Camaro has 245 hp and it will run away from the 400E. I think Deanyel is right about the rear end ratios. If you want performance, I don't think the 400E is the car for you. Maybe the 500E is a different animal, even though it only has 50 hp more.

Over the years, I've learned to accept and appreciate the car for what it is--a high quality sedan (probably one of the best ever built)--but not a hot rod.
