Its a stage 3 crow cam plus it has a stage 4 performance chip
What is a "stage"? Every cam manufacturers "stage" is different. Can't tell you anything without specs. Crow's "stage 3" is going to be different to Camtech's "stage 3" which will be different to Lunati's "stage 3". Just link the cam you bought.
Tuners don't tune in "stages", otherwise it would be some tickbox exercise and everybody would tune cars themselves. Without anything to go on like a dyno sheet or any other info, we can't tell you anything. If it's an ebay chip it's likely garbage. Also worth mentioning that typically a cam change (usually especially something that markets itself as "stage 3") really needs to be dyno tuned.
"Stage" is a marketing term. Can't tell you anything unless you give actual part details like the actual specs or part number of the cam etc...
