Sequential has smaller PWs at idle and part throttle, which is where some large injectors lose linearity. If you are using a short runner intake and cams, this might cause a lumpy idle and erratic part throttle cruise.
In terms of sizing, if you want 500hp, you still need a 500hp injector whether you are sequential or batched.
I had great success with Denso 1220 (500cc) and EV14 (550cc) injectors. Bosch green top 440s and Delphi gave very poor atomisation at idle.

ok.
I have some 950cc at the moment but have been looking at the EV14 1000cc as they have been said to work great at low rpm.
The 950cc i have are no particular brand just have GT950 on them so will see how they are when the car is running.
I will be running the engine in before i change over my current efi for the S80.

Re: VR6T info
I have run some Xspurt 1000's (EV14 1000cc) on a fairly standard WRX 2L and idled beautifully, could lean out to 17:1 consistently if I wanted (for example).
Main reason being dead-time table supplied meant that it responded properly. I refuse to fit injectors that don't come with a proper dead-time vs voltage table now, its not worth the frustration.
And I know DTA has that function to work it out, but at every voltage in the range...? - not worth my time testing.

Re: VR6T info
what is the recommended map sensor to use.
Easiest map sensor for me to get is a Motorola model.

Re: VR6T info
That is Gauge type so won't measure vacuum?

Re: VR6T info
Use the GM 3 bar. DTA have a table for it included in the software.
Re: VR6T info
i will have to shop around and see what i can get.
