My neighbor has an 86 Andial 930. It was destroyed in a fire Oct 2010. She had it completely refurbished with paint, seals, plastics, rubber and interior. Car still started and ran fine after fire. Wiring harness was unharmed and no signs of damage. Shop removed intercooler and some hardware to detail/clean and or paint. She asked me to drive it for her stating it's not getting any boost. Said boost used to come in about 3000 rpm. I ran it up to 4000 rpm at shift points for 1st,2nd and 3rd without any boost. Looks as though all hoses are where they should be. I have a 96 993 TT and know where everything is on that. Not sure where to start on her car. Any ideas so I can eliminate the obvious??? Thanks
