Alisport did intercooler removed cat, EGR blanked, ITG air filter. I had an alisport plug in chip (plugs straight into the seriel lead where the fuse box is). It makes an amazing difference. But be warned On kickdown it was like a james bond smoke screen out of the back. It was also pushing up my exhaust gas temperatues up. If you look on your turbo manifold there is like a flat disc (core plug lookalike) I was spanking it up the motorway when the plug popped out. Drifted it back in but it kept popping out so had to have it welded in place in the end. Garage reckoned it was getting too hot and thats why it popped out. I now live without the chip lugged in. Cost me around £150 i think for the chip thats sits in my glovebox. made acceleration fantastic but 300 tdis font really liek getting too hot so took it off to spare the engine. May be better to go for a more expensive but tailored to your engine remap You may get less power but probably better for the engine.
