Assuming this is a 5 gal batch I get a mash pH prediction of ~5.3 for 8 oz of acid malt. It's only 4% of the grist and I think you should be fine.
Are you able to test mash pH? I would be interesting to see where your mash pH actually ends up given the rather large discrepancy between the Brewer's Friend calculator and Brun' Water.
