Having now run the Twintercooler for almost a month (and having fitted a Miltek Race Cat at the same time) i have a problem.
Acceleration feels flatter. Even the guys who fitted it thought it felt like it had less oomph which they suggested may be lag?
It could be many things of course, it's quieter for a start, which could be the air getting out quicker through the new cat and could make it 'feel' slower - but it really done seem to have lost a lot of the urgency it had flipping up through the gears before these mods.
Anyone have any ideas about the Twintercooler causing lag, or even the extra weight of the thing?
Thanks
Al
