i just installed a cam a little more aggresive that stock (262 duration), now after finally getting it to idle decently, and not bog out when starting from a stand still, the car wants to die when i brake. it seems that when i brake the brake booster takes away or gives to much vacuum (not sure what it actually does) and makes my car dip down to 500 rpm, idle is set at 1200, a bit high but i cant make the car idle better, any lower and it's kinda funny. but anyways i was wondering if anyone knew any solutions to my brake booster taking too much vacuum? thanks in advance if you have any possible solutions and for taking the time to look.
