Done a bit of work on my mates Amc ls turbo drag car.
It hit boost cut the other day in top gear when testing. Previous owner had started fitting a co2 boost controller and pipework bit all over the place. Piped wastegate up to turbo housing and overboost was cured but boost too low around 6-7psi when its mapped for 15psi.
His laptop is broke so couldnt set up a mac valve and hes booked up to run at doorslammers this weekend. Map on it appears to be safe so went oldskool and stuck a bleed valve on it. Bleed valve worked great and boost was turned up to 12psi after a bit of road testing. Fuelling was safe as houses in the mid 11s. No idea on power but its done a 10sec qtr previously and it certainly goes well.
