Default is the TCD necessary with stg 3- running around 16-17 psi (is that a safe area with a 5 bar fpr)?

and is the X able to adapt to the 5 bar fpr so the mix will not be rich ar lower rpm ?
and what other tweaks can be made (timing) ?
TIA !

Default You need Lemmi-tweaks with a 5 Bar FBR with GIAC X...

As for the TCD, I would say it is not necessary but strongly recommended if you don't want hickups at mid-high RPM...

Default Alex that was my previous setup before. I was running about 16.5psi during

the summer with 5 bar fpr. I would turn down the boost to about 15psi for winter then. I ran the X chip also with tcd and mbc too.

Default Not that I remember. Just used the x-chip with mbc set to 16.5psi for summer with TCD

and didn't have issues. Piggy recommended during winter though to turn down to 15psi because of stock injectors.

Default I'd say you're wrong on all counts. Sorry, but feel compelled to correct you.

I already replied to lemieux's e-mail on this, but want to correct the misinformation here. Many have run just fine with 5bar on X chip with MBC and *no lemmitweaks*. Also, you definitely need a TCD to run over 1 bar on X chip near redline or else you will just cut throttle ~6,000 RPM.

Default Denser air in cooler weather=higher airflow #s=more fuel injected into the system

You didn't have any tweaks on your stage 3- setup.
