Increased Boost Questions...

[black_gtst]

hey, i asked this question in another thread but didnt get an answer so just thought id start a post n ask.

got an r33, minor mods include hks pod with heat sheild, fujitsubo 3.5 cat back, blitz bov.

i want to install a turbotech boost tee and bump it up to aroung 10 psi. been told i need a fuel cut defender but the car will misfire at about 5000rpm and want to know how i stop this? also is there anything else i need to do to safely bump it up??

thanks heaps

PowerFC will solve this problem.

PowerFC will not necessarily solve the misfire issue.

Yes, it will get aroung the R&R issues, but I have just installed a PowerFC and am still missing at ~5000rpm with anything over 14psi.

My coils aren't the issue either because I have done a Bosch coil pack convesion and even then I had to gap my plugs to .6

I am beginning to suspect there is a voltage drop to the coils at full load because the miss only happens at WOT. If I give it half throttle it will rev cleanly all the way to redline, but give it full throttle and it shits itself.

In summary, try gapping your plugs to .6

Running a little rich perhaps?

The PFC has been tuned by a highly respected Brisbane tuner, so I would doubt it.

yeah just do it. If it wont rev like it did b4 remove it do a few more mods and than put it back in. you will find it quicker for about a week and then you will be looking for more power
