Engine/Transmission (1998.5 - 2002) Difference between the 215HP and the 235HP engine

[Pit Bull]

I know 20HP



My 2000 auto is a 215HP the 2001 auto is 235HP are the engines the same except for a software program that restricts my HP? My 2000 Service manual does not address the difference in HP or any difference in the parts of the engine.

Turbo's are different size, the 01 being smaller for quicker spool up.

from what I did read, the programing is different. The biggest thing was the fueling. while you have more power while in gear, when the auto wants to shift the power is reduced during the shift until it's complete. This why there's less chance of slipping and burning things up in the slush box.

It looks like 18 of the 20hp gain are in the injectors,and the gains are given back during the shift on the 01's. I have a 2000,my dad has a 2001,both are auto's both had 4. 10'. The 01 felt noticeeably quicker,and stronger,the difference is easy to feel. A set of injectors will even them right out,since 275's give 33hp on an 01,and 50 hp on a 2000.
