Car runs fine except sometimes when i slow down sometimes the rpms drop really low to like 400 rpms and usually it will fix it self a few seconds after i come to a complete stop. Sometimes though it will stall, when i feel it about to stall i put a little gas and it usually fixes itself. Car has turbo in it.
1) if i dyno tune it will it help?
2) i think when it stall it is because the engine isn't getting any gas for some reason.
