HKS 2540s not boosting?

[MidnightGTR]

all sorted now.

I'd get your Dump pipes change as it will help exhaust gas flow out of your turbo's and try changing the timing on your cam gears, as it could be set wrong and not letting full gasses out to drive the turbo's to spool earlier.

If all else fails, it might pay to look into fitting some aftermarket cams.

This WILL help

Also, you said that you're hitting full boost at 6,000rpm.

Increasing the duty cycle values UNDER 6,000rpm should cause it to spool up a little quicker. Give that a go also. I did this with my car, it would build boost a lot quicker, but be careful as it caused mine to spike occasionally.

6,000rpm seems very late though.....

Full boost at 6000rpm is normal for 2540's isn't it???

HKS GT2540 are very lag turbo,full boost around 5500RPM.(depend what boost you run)

GT2530 are much better turbo than GT2540,

change turbo small,it will fix the problem

Im only 15 and dont really know all that much so please correct me if need be, but being 2540s, wouldnt they need more than 1 bar to really start kickin? Reading about a set of turbos on a R32 GTR that were bigger than 2540s a while ago, said that they didnt really start much at all until 22psi, but at a start at 4650rpm.

Does she need more boost?
