Cars always struggled to make power with low boost! Previous tunes are as follows

280rwkw 15psi

305rwkw 15psi (new valve springs)

322rwkw 17psi

344 rwkw 17psi E85

305rwkw 18psi (new box & stally + 20" rims)

335rwkw 18psi E85 (new box & stally + 20" rims)

When you get your car tuned should you put the stanard 17's on or the 19's that will be on the car when driven around.

probably drives around with the 20s. I got mine tuned with 20s that I use everyday

Kosij also the power seems abit low and especially for the amount boost!

my manual bf xr6t made 308@15psi with the same mods as yours and then found the internals of the CAT bent out of shape and reduced the flow. gutted it and made 355 before the retune. so maybe something to consider checking out .

Might be time to upgrade those injectors Josh.

Yeah definitely. They're the limit atm. The dyno number was on a fairly exaggerated dyno so I don't think it's tuned too high to be a problem.

Next will be injectors, intercooler, fuel pump and another tune probably in over a year though.
