ok so i have the green relays and was wondering if i should switch over to the blue relays. but then i started thinking and i had my car tuned with the green ones and was wondering if i switched over to the blue ones, would that affect my tune (afr's)? might be a dumb question. idk.

 

I had a customer on the black ones with wild AFR swings swap over to the blue's yesterday and now everything is back to where I had originally tuned it.

that being said as long as your green ones were good while tuned, the blue should put the fuel in the same place. http://www.mellonracing.com/index.ph...roducts_id=317

 

Is this for a Evo 8? 9? Or 10?

 

^ just for the 10s, which is why this is in the X forums

 

Is that for just one?

 

I have a 2011 gsr and was suprised to find that I have the black FP relay. Is it ok to run the black FP relay stock? I'm still breaking in the car and don't plan on modding the engine for at least 3-6 months.

 

I noticed Taylor's 2011 we tuned the other day had all black relays. I'm not sure why they've gotten away from the blue. probably just another manufacturer that did them less expensive heh.

 

I have the 3 blue relays but my fuel pump is the green relay. I've heard that the blue ones are better in cold temps, but the green ones are boss when it comes to durability. Although all colors of the rainbow have been known to fail

 

My 2011 also came with the black relay. Ordered the blue relay yesterday.
