This would be on a track car. I’ve heard of getting a new tuned chip, but a couple of people have mentioned upgrading the injectors. Any feedback would be appreciated.
Thanks

The 964 injector flow 195cc per minute. nor recommended for 3.8
993 injectors flow 235 cc per minute. barely acceptable for 3.8 as the y are at 100% duty cycle at max rpm
generally a 320 cc per min injector is preferred
