rrm piggey back

After seeing what happened with Mpitera's exhaust, I'm not going to buy anything from RRM, but I thought I remember it saying something about gains, but I just looked and it doesn't. E-mail them I guess, see if that helps. The thing is though, it's a program that let's you go into it and change everything yourself. So, they might not have a specific gain amount on hp or ft./lbs. because everyone adjusts it their own way. I know that's how a friend of mine's works, it came with a computer program and you can tune it yourself and all that jazz. But, they should say what the maximum amount that you are able to add is.

 

Volo vp12 or something like that. Mpitera has that instead of rrm's piggy. It's practically the same thing except you can't tune it I believe. But the piggy is a bit of a hassle to install because it has to be spliced into the wiring of the ecu. As for gains. It's there. Not much though since you are driving a 4g94. All you have is intake right now right? I wouldnt suggest gettin it just yet if that's all you have. If you get a header downpipe exhaust and get that the most you will gain with a proper tune would be 5hp at the crank so like 4hp at the wheels. I wouldnt suggest it if you want more speed. But once you get all that it will help you not to run too lean or too rich and cause cataclysmic loss of life. But it helps a lot with back fire issues. Or you can do what I did and force my engine to relearn with everything I have. It took over 7 months and perfect weather for a month b4 i got it right but very minimal backfire issues.

 

installing the rrm piggy is like idiot proof, just get some quick splices from your local part store, splice where need be and the boom all done. restart your ecu and let the car idle, relearn, then take it out for a drive. everyone love the piggy on Evom.net most say it pulls in forth and fifth gear like if it was in third. awesome mod.
