So, lets get into the point
I used to have GTM fuel rails and for those of you who don't know about my build, the picture in my signature will direct you to my build thread
With GTM fuel rails the car have some lean spot on low rpm (say from 1500 to 3500) and when I say lean it means the AFR gauge is showing ZEROs instead of high numbers.
When I first saw CJM advertising their fuel rails that has these stock dampers it had me thinking why these got the dampers and GTM's product doesn't. I called Charles and all he said was I will not be disappointed if im switching to these. I paid for the fuel rails the second he said that and it was a pleasure to deal with him!
Fast forward I got busy and couldn't install the fuel rails till now and lemme tell you, what im about to write is honest and proven.
First of all there is not a single lean spot in entire RPM, I watched the whole RPM range from idle all the way to redline.
Second, the drivability changed in a better way.
Third, adjusting fuel by tune is recommended after changing from GTM to CJM
My friend was with me the time I was testing these rails and I couldn't stop talking and complaining about these improvement. Of course, he was having no idea what I'm talking about as these days people think fuel rails are all the same just like I did in the past
To be honest, I wanted to find a lean spot to call Charles to complain, report and see if he can improve these but nope, I failed and I was very impressed.
I usually don't make a thread to make a review on something but this product exceeded my expectation so I had to return the favor back.
You Charles are the best to communicate with and later on when you release a new product I will know with eyes closed that it will be tested and drivability proven
Here a picture of GTM fuel rails that I had.
I will post picture of my CJM rails when I have a chance to capture some.
Cheers.
