Has anyone here ever been back to Vince after a re-map and asked him to up the power even further? Is this possible? What else can I fit/remove/tweak to give me even more torque and power? Fuel additives? Exhaust? Cams? Is there anything else?
Well, the only way to get the power you want out of your 1.4 TDI engine (ca 150 HP) is fitting a bigger turbo charger. The size of your current intercooler will be still OK for 150 HP. Also no stronger clutch and no different gearbox is required.
Just make a trip to Switzerland to the head of

Besides different turbochargers he offers a full range of diagnostics and also of bigger fuel PD injection elements (larger fuel volume to burn = even more power).
150 HP kit
(this kit actually is offered for the "ATL" 90 HP 1.4 TDI engine but Mr. Kaufmann will probably do that conversion for the 75 HP "AMF" or "BHC" 1.4 TDI engine as well:

Last not least, if you feel the need for even more boost you may add a high quality water injection system to your new turbo-conversion.
