Ahh... That Post... Takes me back..... O yes, all the mods are still in there including the spring mod. The only difference is that now I have both of the springs installed. No codes in the PCM at all.
I know that it's Getto, but as long as it does the work, it is fine with me. It takes me less than 30 secconds to return it to stock and less than a minute to install.
I run my car at 15PSI constant and no codes with this setup.
