Just wondering who has used any of the Modules available for the 3.0 CRD powered Grand Cherokee.

Has anyone used a V-TECH redbox module?

Or the V-Tech Chip tuning/ECU flash??

 

I drive a GC CRD 3.0 2008. Upgraded with a Saretz Gmbh tuning box in December 2009. Great power increase and got rid of most of the turbo lag. Now they send me twice the tuning box I purchased from them on ebay. It gave me problems were the engine would stall at idle, not a good thing when waiting for the red light to turn green :). Anyway Saretz send me an upgraded box which is slightly more expensive. I have been using it for 2+ month and its great, it solved the stalling problems. When going for service I just remove the tuning box and no one will know, I have the extended warranty. One more thing I had some trouble installing the unit which should be plug and play, however the connector on the common rail end is hard to get at, so it takes a bit of work and time. I thought I let you know about my tuning box since I am happy, I do not know about the other competitors in the market. I suggest to read some of the reviews. Best ericv1717
