PTE injector sizing

[questhe]

I just installed a set of PTE 880 cc injectors, replacing my RC 550s.

I found that the compensation changed less than expected, indicating that the injectors are not as large as advertised.

If my RC550s are accurate, my PTE 880s are really about 800 cc.

Has anyone else experienced this kind difference (10%) between advertised and actual?

Quite a few members on the DSMlink forums have had this same issue with PTE injectors, too. I don't recall them being off that much, though. Most of the time it was just a little off. I've read numerous times that PTE 880's flowed closer to 850's. I just picked up a set of PTE 850's, so I'll let you know how mine turn out once I get off my lazy ass as install/tune them
