After fitting new injectors I have had a few problems to say the least. Trouble is as I did a bit of other upgrading/ repairing at same time so don't really know what is wrong.

The thing I need to know is what should the car run like with larger injectors but still an SE chip for standard 370cc injectors.

Thing is I have tried JWT chip set up for 555 injectors and it ran absolutely cr@p, wouldn't even idle, popped, coughed and spluttered all up road. So I put the old one back (SE). It will now idle reasonable but not brilliant and will run fine up the road.

Do you guys think the injectors are not really 550cc injectors:mad: or the chip will not work in my car.

 

Getting despirate now.:(

Do you have the part number of the injectors you fitted?

What colour was the plastic on the plug?

the plasic was white and they where made by Venom. They where bought cheap from someone in the states, but the box stated 6x550cc.

I've never heard of Venom injectors for the Z & I was looking for 555's for about 6months. Best ask on ttnet.
