Hi Heinz,
My car is a 2014 Sigma 4/4 it has Jenvey TBs and Omex ecu. The manifold and exhaust are Librands and that is the only upgrades it has. I had the set up done by Techniques.
The car was standard before the upgrade and nothing was happening under 3500 revs so in normal driving I had to use the gearbox more than I wanted to. Now in traffic I can use 5th gear. When I ordered the car I went for the Plus 4 body as I like the look but the wider tyres were no fun on corners so another reason for more power and torque.
Tried to PM you but it came up with some thing about a limit?
