I have a Vortech vs-1, custom chip, adj. fuel pressure reg, stock injectors, and stock mass air. My question is when I'm at Idle the car acts as if it's loading up on fuel but then when you get on it reads as if it's running lean. I bumped up the fuel pressure but that made the idle worse and it still runs somewhat lean. Any suggestions

 

Check to make sure your fuel pump is working properly. Also, your injectors may be too small. How much boost you runnin? If you're running 7+ psi, your injectors are probably hurting your top end performance.
