99 uk, dawes up to 1.1 bar in 5th.
been cold today and this morning it was peaking at 1.15 close to 1.2 bar.
where is fuel cut on a 99 with 801ecu please?
was expecting a fuel cut brick wall so went easy on boost.

Not sure what the actual figure is but it is time realted also ie may be 1.2 bar but for 2 seconds or so. If the boost drops slightly below the tollerance within this time it will not cut

I think it's something like 17.3psi (1.17bar), held for a few seconds...

ok guys cheers, next question:
with a new uprated pump, regulator and a cut defencer, what is safe boost on std internals?

What turbo and intercooler you got? To work it all out safely, you could do with the compressor map for your turbo/compressor...

As above, depends on turbo and whether or not you're talking of a remap or on the standard ae801 map.

If you're sticking with the stock td04l you won't be able to hold 1 bar over 6000rpm-ish (therefore capping max power) but it'll happily run 1.3bar midrange, with "useful" midrange punch. This is with a standard TMIC. You will probably need to use some form of octane booster for this though as the load maps on the standard ecu will be maxed out causing timing to be too advanced between 4500-5500rpm at this boost. Fuelling won't be a problem even without an uprated pump and regulator, as long as you're sticking with the stock td04l.
