For some reason, I took the car out this morning and when WOT in first gear I only get about 0.5 bar, then in second gear and in the rest of the gear I'll get my full boost which was 1.0 bar. I don't know what could cause this as all the vacum line looks to be there and good.

I'm running a T04S single and HKS EVC boost controller.

 

not enough load to spool such a large turbo in 1st gear

 

HAHA me too. I only get about .45 BAR of boost in first. Then in all of the other gears I hit 1.15 BAR.

 

What exactly do you mean? So are you saying this is normal? I was just wandering. Because honestly when I first bought the car, it was too damn fast that I had to just concentrate on the road. But I've been paying attention lately to boost. And first gear the most boost I get will be 0.5 bar and then gradually going to 0.8 bar when nearing redline...
Then when shifting in the rest of the gears, it's boosting flawlessly...

 

its normal, my car with its oversized previous setup saw very little boost in first gear, i hope to get atleast 9lbs now

 

This is 100% normal because the gear winds out too fast.

 

Oh really? and you are running on a GT42R with a Half-Bridge?

How much HP does your car make? Mine makes 402 at 14PSI.
Although I do hear like theres a loud leak in first gear, similar to when I use to had stock twins...
But then I guess it's cool, cause in the rest of the gear, it feels so damn good.

 

I make 450whp at 17psi and 503whp at 22psi

 

Cool...
Thanks guys. Thought I was going to have to go through another deja vu nightmare of the stock twins.

 

If you want to take off with full boost in 1st gear get a two-step boost controller.

But then again, unless you are on SERIOUS SLICKS you wont have enough traction to use it anyway.

 

I get full boost in first gear on my gt35r. Maybe my turbo is smaller therefore I get the full boost in first gear.
