> your not going to be able to have your car run off of anything bigger than 550s, you can sure bore out the stock fuel rail to try to squeeze a little more… but assuming you know how these cars will dump fuel at boost at a maximum injector rate at boost, so if your not making over 300whp prolly not worth it to through in 550s, but and with bigger than 550s the car will not idle…

I’ll take the fuel rail for $20. I have 550’s now, but that won’t be enough for the boost I plan to run after I get the haltech.
