Only had the car together with the 20g for a week before I broke it. 
I was running 15 PSI and had plenty of fuel. I should be able to let you know in a week or two how she does @ about 18-20 PSI. 
19 psi no problems on pump gas with the 550s. Need to upgrade my 2.5 exhaust and see how they hold up then.
