hey all,
i just got a new 1994 e420 and saw some performance chips on ebay for them. has anyone put this in their e420 or heard of anyone who has? it says it improves gas milage and HP. If anyone has any input on this it would help alot. Thanks.
I saw those too. Not saying they don't work as I have no experience with them, but I have heard too many horror stories with this type of thing being sold on eBay.
In short, unless you can find sombody who has used the exact thing you are looking at, stay far, far, away from this stuff.
Im w/ colorado on this one as well! Stay twards MB tuners like the renntechs, kleeman, powerchip dot com, lorinser, etc. Buying a chip on e-bay is like buying a fur coat at K-mart[xx(]. Besides, this primitive type chip your looking at most likely does not have a re-program feature if ecu is plugged into at the dealer to check for codes.
