Thread: Raising turbo boost pressure D2

I've gone +4 turns and have only hit cut-off once (more like a momentary stutter). It was floored racing a ricer through a roundabout

I reckon I could go another 1/2 turn easily as I hardly ever floor it

Hi

I think I will start at 2 turns and go from there after I get the Exhaust done

thanks

Just checking back on what boost pressure is sane/sensible to use as I realised that mine is peaking out at 20.35 psi

And here I was thinking I really should try turning up the boost by 2 turns. Obviously this had been tweaked by the PO.

I find that the d2 really feels like it is limiting at 3000rpm under load when climbing hills. I'm wondering if I might be better off winding the boost back a bit so it's not running so close to the ECU over boost limit?

cheers
Paul

Dont bet on it... The D2 I got from Dad (was new to him) when first tuned kept overboosting..

It was stock - even the dealer commented it went 'better' than most...

When we kept overboosting and throwing into limp mode we put a memory boost guage on it... 22psi - as shipped from the factory

And yes - on the dyno... Pulling the boost back to 19 psi got us an extra 12 kw at the tyres....

Looks like pulling the boost back a little might be worthwhile then.
