90BHP Non PD Stage 2 Remap (GOLF)

[B5-Passat-1988]

Just had ECU chipped, car is now pushing v close to 130BHP. I don't want to go to crazy bhp levels but the tuner recommended a bigger turbo. My 90BHP model has the smaller wastegate turbo so I obviously need a bigger wastegate turbo. Would this one off a 115PD be any use? Part number GT1749V? If so any ideas on BHP increase? cheers!

For anyone seeking similar advice, I have been told (BY A PROFESSIONAL) that it will throw out between 160 and 180BHP with a bigger turbo and injectors, taking into account that the ECU is already "chipped". As for the 115bhp TDI PD Golf turbocharger (part number GT1749V)? It is "not compatible" but with slight altering (of fixings/fittings) it will be. Apparently if your TDI has a standard wastegate turbocharger instead of a VNT turbocharger, you need to buy a bigger wastegate turbo or convert your own for a VNT turbocharger. You may also be able to use some Japanese car's wastegate turbochargers, examples - Nissan.
