Ok, So I've installed Twin HKS GT2530's on my RB26...

And Im having a huge problem making power. The car is very laggy, I cant even get to 15PSI before about 5800RPM. Rediculous, it feels like a GT-42.

And I've only made about 400WHP so far, C16, turning up the boost to 18-20 PSI. Its very very laggy-

Im using the same computer and tuning guy as I did the last 5 cars that all made good power, and the same wiring guy, ive checked for boost leaks and im out of ideas. everything was brand new when It went on.

Did you happen to grind the exhaust manifolds, to match the exhaust inlet for the turbos?

Your tuner should be able to adjust the timing for better spool as well.

That is way laggy.

Turned out to be the actuators.

Then we sold the car the next day.

I know you, youre that guy in Florida that sells JDM cars. Near Davie or somewhere.
