   Hi ppl.
   I already fit my turbo on my vts but I put an 200cc injector and only one.
   I would like to know the best size to put.
   My car only can run at 25% trottle to 4000 rpm and then it cut, it is running lean, and my ideia is the injector isn´t enaught for the job.
   I am using sig con and mf2.
   Please tell me the injector you use for this conversion.
   Please help quick.

   Hi brian.
   My input gain is set to 20 turns clock wise.
   I already fitted a 320cc injector but it didn´t worked right. I can only press 25% throttle if i fully press the gas the mixture runs lean.
   I didn't connect the 9 pin of the sig con (the amplified not clamped i think) Is it necessary?
   I don't know for sure if my problem isn't with the values of the sig con, i had a standard value of 4,48v with standard map sensor (with ignition on, engine stopped) and at idle a standard value of 1.76v.
   Now i have set a value with cal2 of 3,60v for ignition on, engine stopped and a value of 2.25v for idle.
   I couldn't get better values with the cal1 and cal2 so i had to split the difference for the min and max values.
   Give me some hints please!!!! URGENT
   Tomorow or even today I will fit a second injector if necessary (the problem might be at the sig con)
   By the way what's your gasoline pressure?.
   If you have msn messenger could you give me your contact?
   Bye thks

   I can`t give you a answer about the sig con because i`m not using one!
   But whit 20 turns clockwise on the input gain and 50% injector rpm set you will ave to run a bit to rich?
   
   My fuel pressure is 3,5/4.0bar!
   and i`m not sure what size my injectors are! but they came off a citroen/peugeot V6 engine!(last type)
   and i can run way too rich!!!!

   I thought injector size was going to be how you used your injections to be most beneficial to other...wink wink if you know what I mean??
   
   I like them big and noisy.....
   
   I just feel so frustrated at times...
