Does anyone know what the blood pressure limits are for an FAA medical
certificate, second or thrid class?

From the AOPA website:

Current Federal Aviation Regulations do not impose blood pressure limits
for any class medical certificate; however, the FAA has established a
policy by which persons with controlled blood pressure may be certified
at any class of medical.

The FAA considers blood pressure controlled when the average sitting
blood pressure does not exceed 155mm mercury systolic and 95mm mercury
diastolic with or without medication. If the blood pressure is
controlled and the required cardiovascular evaluation is provided at the
time of examination, the aviation medical examiner may issue the medical
certificate, as indicated in the revised Guide for Aviation Medical
Examiners.

The FAA currently allows most FDA-approved anti-hypertension agents,
including diuretics, angiotensin converting enzyme (ACE) inhibitors,
alpha-adrenergic blocking agents, beta-adrenergic blocking agents,
calcium channel blocking agents, direct vasodilators, or combinations of
these agents.
