on a t3/t04e on a sr i will be making upwards of 400whp with 20psi Thanks n i hink i got what i am gonna do. get it tuned at low boost first on 93 octane, then fill it up with 100 octane n get it tuned at 20 psi. Just have to buy a couple of gas cans to keep some 100 octane around.

also how hard would it be to have an exta fuel cell installed? like a sepearate tank n pump so i can have a 93 octane primary and a 100 octane secondary.
