05 Nissan Frontier CC 6 spd
my car is flashed.

mods:

Spool FMIC
Spool CAI
Ion exhaust
93 octane
colder plugs

I know for a stock flashed MSP, I should not boost more than 9 psi, but since the bigger FMIC and exhaust help cool thing down would I be able to boost 12 psi safely?
 
as high as you can get without getting knock/detonation. but i would vote for less than 9psi, just to be safe.
 
03MSPRO - given you can remove the boost cut, we've been able to safely boost up to 14psi up here ~ 3/4mi above sea-level on cars equipped with our stage 1 FMIC, CAI and turbo-back system. This is on 91 octane fuel. Boost controller was an APEX-i AVC-R

What happens if you run over 9psi on a flashed car? Is there anyway to unflash it???

nope i haven't heard of anyone able to go back to the orginal ecu programming. you could trade maybe with someone.....
 
discreet is boosting 12 psi daily and his is flashed. his is lightly modded. but probably i'd prolly run 9 psi to be safe until you can get some kind of fuel controller.

Is that on a flashed car?
 
with "only" 2psi you can run well in the 14's.....isn't that enough for daily driving??
 
iON - wow 17psi?

With some talks here with the fastest P5 (microtech tunned) in PR, he told me the stock rods will go south @ 18psi. thats on a T3 or a bigger turbo.
Can you tell me about that knocklink unit? I been thinking on getting the msd knock detection unit.

igdrasil - 17 psi @ ~ 3/4 above sea-level is ~ 16psi @ sea level.

The knock link is a good "just-in-case" device. It can be set to quite sensitive levels so that it'll light up at any sign of knock. We use it alot when tuning Subarus which have noiser valvetrain then Mazdas.

A cheap DIY knock sensor is using a microphone, a small amp, and a set of head phones. Listen with your own ears. :)
