I was having issues with the fuel pressure at 30 psi of boost. I wasn't getting 1:1. I wasn't leaning out thanks to the injectors compensating. I didn't want the injectors to be compensating each time I ran high boost, I decided to upgraded to the Walbro E85 pumps. Issue solved, now I'm getting 1:1 confirmed all the way up to 31 psi of boost.
