ots stage 2 fmic question about boost, maybe issues

[inseong]

hello, im having a little bit of trouble if anyone can help me. im aware that most people lost 1-3 psi after upgrading to a fmic b/c of the extra piping and maybe more efficiency? but im spiking 17-18 and it slowly goes to 16psi mid range and top end tapers down to just under 15 psi. im fully bolted with hpfp and seals.. afr is in the 11's and no knock. do you think i have a boost leak or maybe a tuning problem?

also i have logs but theyre in csv format? how do i post them up here? also i noticed even tho im fully bolted in 75ish weather here in philly, my load never seems to pass 1.8x, is this normal for a fully bolted stage 2 car?

What are people boosting on stage 2fmic map?

I'm not running a stage 2 map, but I have no pressure loss with my fmic. It has the shorter piping route so maybe thats why. But I thought that you only got boost lag with fmic's, not boost loss, doesn't make any sense. The turbo is still putting out the same boost, but it just takes longer to create pressure because of the added piping. Anyway, good luck.

Huh, I was under the impression that afmic will be more efficient thus loss of psi

It's normal with OTS Maps. When flashing the AP (not the site) tells you that it will boost high then tamper down from there. If you want to boost higher through out the rpms then get a pro tune. I think it's better this way for the tuner to be present and tell you if it is safe to run your car at high boost.

Depending on the version of ATR that you are using, your load may be limited by your throttle req load-x gear normal bat tables.

Sorry to dig up an old thread, but if you need a hand, I may be able to help.
