Big difference in the torque.

 

Much more like it :D

 

yep feels good, didnt think it would be that much of a difference but it is! Its also ironed out a few flat spots I had before or hesitation, I think because its bypassed some VSV which may have been slightly faulty

You have to be in Manu mode with O/D off. Start with the revs as low as you can, avoiding kickdown

 

Hmm....Does that mean I have to put my traction control fuse back in? I pulled it out as soon as I bought the car lol.

 

Also I have a hi stall torque convertor installed. Will that make it trickey?

 

I read something once about earthing out a pin on the ECU to get it to hold in 3rd gear?
