Hi,
I have been looking for a performance chip for my Amazon 4.2 VX but can't seem to find any available for this engine. Superchips, Hypertech, & Jet are all reputable companies that have been around for a long time but do not list a chip. I have found various offerings on ebay but none from reputable firms, some promising power increases of @50hp and huge amounts of torque along with fuel savings. Does anyone have any experience of 'chipping' a 4.2TD Amazon? I have read that its not possible to do effectively because the engine isn't a 'common rail diesel', but its all conflicting with other sites i've read that say it is possible. I'm very confused any advice on this sort of thing would be appreciated.
