Guys,
I have a walbro, colder plugs, and FCD going in tomorrow. I also have a boost controller already fitted.
J-spec not UK.
I have a 2nd de-cat, and a straight though pipe with no muffler. The first cat is still there, and I want to keep it for noise reasons and to pass MOT.
I realise that I can't go "BPU" with the 1st cat still in place, but I do want to increase the boost using the controller.
Currently boosting at 0.95 ish as I haven't fitted the other parts yet.
Had some advice from a well respected member of this forum who I spoke to at Supra Pod that I could leave the first cat still in (I guess the first cat does the same job as a RR *grin*) and up the boost.
Can I have some opinions please, it is safe to gradually increase the boost up to 1.2 bar or so? More importantly, how will I know if it's causing problems?
Thanks!
James
