For example, When I first did the Whipple with 8 psi pulley, cat delete pipes, LPE HPFP, LT4 injectors, LT5 tb, RF standard. It made 600whp and would run Full E(82%). When I switched to 3.375 pulley(9psi), I had to drop to E70. Then I did Big Gulp/103 and was limited to E45. So, I had to drop E content 25% just for those mods. I then did a 3.25 pulley and XDI +30 and keep it around E60.

Now before someone says, "why didn't you go port", well this was back when DI fueling mods was cheaper than port". THP and Atlas didn't exist.

Either way, Point is air inlet mods on a PD setup makes a significant difference!! Especially when you get 700whp + as previously mentioned.
As always great input King! It's crazy how capable it is to make big horsepower numbers with these cars. I was telling the tuner, these cars should have come from the factory tuned for E. It's like a whole new car. To be fully transparent, I'm probably going to have them install the 2 pulleys and kooks. Than when funds allow 103mm intake with throttle body and BG. Tuner I imagine should be able to remote tune for the 103mm without issue. Unless it's more difficult than i'm making it out to be (adding the 103mm bits and pieces).
