Help please

Hi. Got the car on the dyno and it's running at 143bhp got it remapped and it's stil running at 143bhp. There going to check the boost. If that is ok does anyone have any ideas why the remap isn't working ?

[Dalo Harkin]

it cant be 147 before the remap and 147 after because the values they change when mapping create more boost and therefore more power.

what car and ECU does it have?

It's a boost prob. I havnt a clue about golfs.

Golf mk4 1.8t 20v havnt a clue about the ecu. Turbo is working its not boosting he said.

Where was it mapped?

If it was down on power to start with they should not have remapped it without sorting the problem.

They done the remap and i took it 4 drive and it didnt feel any different. They put it on the dyno and it said 143 bhp after the remap. The boost was only going at 0.3 or 3 bar on the dyno not to sure about boost readings. He took off some vacuum hose to the turbo and done the dyno run again and it boosted at 167 bhp. Told me it cud b n75. Replaced that but dosnt feel any diff. Does anyone have any ideas please?
