Boost Higer When Going Faster?

... does that happen? reason being that at speeds below say 90ish i can take it to the limiter and dont hit fuel cut.... but at higher speeds i hit what i think is fuel cut way before i get to the red line!?

it happens because at higher speeds there's more aerodynamic drag (vs. very little at low speed) and therefore more load on the engine and more boost. That and/or cos you're in a higher gear too.

Someone will be along soon to explain properly..

time for a fuel cut defender then huh? what bar will i be boosting at with a rear decat once its fitted and at what pressure does the fuel cut kick in with out the defender?... 0.8 bar???(jspec).

At what boost level does this happen?

if i had a boost gauge id tell u! lol what should i be hitting with just a rear decat?

It's irrelevant if you don't have a boost gauge

FFS

Post again when you have a boost gauge. One that has Peak Hold

I'd consider buying a boost gauge before an FCD. Or get both. With cat #2 gone & a aftermarket exhaust .. maybe 0.9 - 1bar (1bar if you're lucky)

Cat #1 is the one to get rid of .. ideally both of them.

so the fuel cut is currently kicking in at 1 bar???? Im not sure i want to tho too much money on getting performance out of it as i know il end up doing more and more and spend £1000's on a single etc... now ive got a taste for speed i might take the easy option... sell it and find 1 supe thats already had the single fitted!

I thought this was normal. I only hit 15psi above 90mph, fuel cut comes shortly after.

its a right bitch huh!
