is this too much boost

[armymanmike]

Me and a friend just fitted a new hks actuator on his gt it's set up at 9psi low boost and I think about 13-14 psi on hi . He hasn't tried it on hi yet as he is scared it's goin to blow up or something . I'm pretty sure it won't but can someone post something to 're assure him please .

That 0.8 bar should be fine mate what mods dose he have ?

[armymanmike]

Okok cool man . Mods are full defo cat hks pipe, blitz filter . Fmic.. think that's it. What psi does fuel cut hit in??

[akyakapotter]

0.9 / 0.95 he will soon no if he hits file cut like hitting a brick wall.

[armymanmike]

Haha sweet mate cheers. Is it possible to creep from .8 to .9 ?? Or shoold we just test with no cars behind lol

[akyakapotter]

Dose he not have an fuel cut defender ? If he dosent id ave it at 0.7 just to be safe

[armymanmike]

No he doesn't. Ok mate well sort that now cheers

Fuel cut differs on every car, only way to find out where his is, is to go and test it out not a big deal if you hit it once just wind the actuator a bit until you have found where its safe! So long as you don't keep hitting it you shall be fine

Lmao 14psi is basicaly 1bar you will defo hit fuel cut especialy with the mods he has!! fuel cut is around .85bar and it will hit more on a cold day to a hot day as air is denser on a cold day. tbh id set it to .6low .8hi and leave it alone till you have the proper supporting mods for 1bar! You will shit the 3rd piston if you run too much boost atm as you havnt said your running an uprated exhuast manifold so the oem restriction will be in place on the third runner. supporting mods befor boost!! Simples!

Just to add has he got a de-cat pipe?

That would be my next modification before turning the boost up any further as it's one less restriction on the turbo.

[armymanmike]

Yes he has a decat. Well we tried hi boost but only for a minute then kept it on low now on low it says boost is at 10 sometimes 11 psi. How is this lol
