I hope all turns out for the best PranK. Go the GCG.... ! You dont 'need' a manual, being a tall fella and all that! (there's no way in hell Id be able to drive the Stagea as a manual, being over 2metres tall).
Ive got a brand new Apexi SITC and the Nismo FPR, and already have a SAFC tuned, etc etc.
Will let you know how fuel economy goes when I have everything retuned for the SITC, FPR, fuel pump, fuel lines, Z32 AFM, etc.
Probably not for another month or so (just waiting on a price from the workshop who'll do the work for me, including retuning the SAFC). I was going to up it to 11psi, but upon reading this thread, I dont think I will!!! (dual stage ebc, tuned at 7 & 10psi)
