Can anyone help me with the following for the GM/Fiat/Alpha/Saab 1.9 turbo diesel: 1. Larger diameter MAF sensor as I have maxed out the OE 60 internal diameter MAF sensor body. Bosch 4 pin plug. 2. Bosch MAP sensor, again 4 pin, 3 bar or more required to allow me to run 1.9 bar. I guess the existing is 2.5 bar as it maxes out at 255kpa. 3. Alternative turbo. I already have a 56 wheel in place of the OE 49 diameter compressor wheel but think I am getting close to max. 4. Does anyone know the power capability of the turbo on the LT35 VW? 5. Someone capable of live mapping as opposed to importing a CDM or EDS/IPF map file. I am hoping to live map on the road or on the rollers and followed by a final road session to take account of the existing mods. Power measured on Scooby Clinic's DynoDynamics was 158 bhp and 234 ft.lbs when I started this some months ago. Last week 230 bhp and 335 ft.lbs. I have very little small diesel tuning knowledge so any input appreciated.
