Flat until 4k

I think you are right its not running like that, its much like your description in your first post. I wonder if im just above 2000rpm off boost most times when I have decided to put my foot down, this would explain why im thinking its flat then I only get one big hit of torque. I'll take it out again tommo... and make sure I try it from bellow 2000. I'll alsoo take some time to read up on the manual mark gave me for the boost controller.

 

Thanks you guys have been more than helpful

 

I think its just a case of getting used to it, after all your used to a 500bhp celica, so will take time to get used to :)

Thanks again guys, had the car out today and i'm slowly getting used to it and how it reacts. Its not so much flat as just not as hard a hit when you get the hit from both turbos at 4000rpm. I like it though and will stick to them running sequential.

 

Car has basic modifications such as air filter, dump valve, evc 4 boost controller, fcd.

 

It still has the cats in, im looking to remove them and put in a 3" system with restrictor ring, what else can I do to get the car to beyond UK spec? Did the UK versions run bigger injectors? Would I need to change the ecu to a UK version?

 

Thanks Again

 

Stuart
