So here's my situation I have 2007 sti it has just over 20k miles and feels like it runs good. Car has had compression test which came back goodCar has been running royal purple most it's life till now shell rotella t I have not decided which will be used forever because I'm waiting on oil analysis test. Car is located in so. California and is forced to run 91 Cali piss but I have cobb ap stage 1 on 91acn map which brings me to my problem. my car is having trouble hitting boost 13.5 in 5th it's also seeing up to -2.5 in knock correction on my datalogs. So should I

A: get catted dp,fuel pump and tune asap for reliability and power but would mean I would have to retune my car months down the road when I get a few more things

or

b: my original plan of getting tune 6 months down the road with catted dp and supporting mods for 300+ hp/tq goals

I just don't know if I should get tune asap to insure my car is running solid.

check for leaks post maf pre turbo... most likely thats your issue. have the AP check the AFR, watch it and try to max out, the narrowband on our cars should read 11.02 on teh AP constantly when WOT. if it doesnt you definatly have a leak.
