From what I read, it provides a 10 to 15hp gain. I read that it is better than the JET and SLP perfomance modules. Has anyone heard of it or tried it? It could be a good or cheaper alternative to the GeFroce and JWT ECU.

 

Doesn't SLP do domestics? Do you mean SGP?

 

This is what they wrote down for th description.

Our Racing-X Performance Module Version 1.0
If you have a stock engine with no or little modification, this is the module for you. The Racing-X Performance Module Version 1.0 is for maximum power increases on a stock vehicle for improved performance under hard throttle conditions such as towing and wide open throttle acceleration. The Version 1.0 Module does not require the replacement or adjustment of any other parts to your vehicle. It provides signal-error protection during extreme operating conditions, the JET & SLP units do not. The Version 1.0 Module (currently the only model available) did NOT require the use of premium fuel during testing, the JET and the SLP units did (Premium fuel will however enhance the performance gains acheived by the Version 1.0 Module). Performance gains are very similar between the JET & Racing-X Performance Module units, however the SLP unit lags behind in most conditions. In many instances (reviews widely available on the internet) the JET unit did not provide any performance increase at all (and in all fairness to JET, other times it did). And best of all, the Version 2.0 Performance Module is tentatively scheduled to be released this summer, at which point Racing-X Performance Group plans to make a cheap upgrade unit for Verion 1.0 owners, allowing them to upgrade to a more aggressive unit when it becomes available (the Version 2.0 Performance Module will be require premium fuel)!
