Most of the turbo setups Ive seen use DSMs with peak to hold injectors... Mainly because theyre cheap and do the same job as more expensive aftermarket injectors... So I should have said most larger injectors that people upgrade too are peak to hold... Plus they respond faster than saturated... And either way u slice it, most cars do come with saturated injectors, infact most that dont are turbo from the factory... Which we all know is a very small amount of cars on the road...
