Has anyone put one of these into their MB? If so, any tips?
I have read a little about the Venom 400 which runs about $300-$400. Seems like a this is the real deal. But do I really need this power box just to get better HP. This has various connection to sensors etc..

There is another Performance Chip by Vole for $90 and connects via the OBD2 Port. Comes programmed with a set of EPROM addresses that directly affect efficiency and performance. When the ECU attempts to read one of these addresses, the VP12 patches the factory value with one from its on-board performance tuned map. It claims not to connect to the IAT which can cause damage.

Need some advice since I lack some knowledge in this field.!

Thanks!
