Twellsie,
The difference is I don't tear around housing estates all night long, and all day for that matter, with no exhaust like a few round here, I have never used mine on an estate, won't even use it near old people or pets etc, f**k me it's not hrad to do is it, lower the soft cut and hard cut job done, all I have done is put on one of my three maps soft cut at 3000rpm , then hard cut at 3300rpm, got bored so have taken it off now, modded yesterday so I can use low or high impdedance injectors now, as greys were only 2.25ohm.
