I've got a 1.25 MK4 fiesta with 90 BHP and 133 nm torque (however car had an exhaust leak at the time so wasn't running 100 percent + my boost valve was standard (wasn't turned up). I've got a remap, full exhaust (including 421 headers and 200 cell cat) msd coil pack and high voltage wires, FSE power boost valve, cone air intake, performance engine mount, slightly higher bar fuel pump and am just about to install a puma 1.7 throttle body (12mm bigger than standard). All in all the car performs amazingly for what it is and couldn't be happier! FYI if you want the 1.7 throttle body it's literally just a bolt on no other things required (38mm standard throttle body which is very restrictive tbh). Pretty much a no brainer tbh! Hope this helped!
