Is a TBE w/o Engine Management Okay... Please Help!

Okay so i already have the Borla "Hush" Catback system on my 06 WRX and I just received my Helix DP w/ CEL fix today and will be installing her tomorrow. Going completely cat-less

My question is, is it safe to run a TBE and no engine management such as UTEC or the Cobb AP? Will it cause problems with my boost pressure that i should be aware of, or anything else that i should worry about?

All advice is greatly appreciated! Thanks guys

No worries, I have been doing it for over a year now. Your max boost will also increase about 1psi.

so with an 06, the max i will push is ~13.5 psi w/o engine management and i have no need to worry about my boost spiking much higher before i have a chance to get my cobb AP?

thanks.

You'll be fine for now. My 1/4 mile time was just with a tbe and intake. I can't wait to see what these RA gears, EM, and some dyno time will get me.

My car is well, it's like 10 lbs of shit in a 5 lb bag...

Just like they said. You're good man. Engine managment will help make it even better though.

+1 i did it for a little over 40 days then got the AP. Then you can turn her up from 13.5 PSI to 17

We don't have emissions testing here. Removing any working emissions equipment is illegal pretty much anywhere in the USA. Yes, the exhaust note will increase cosiderably depending on which exhaust that you choose. The Helix is pretty loud, but it comes with a silencer.

I'd say go for it, just keep the stock exhaust for inspection and testing. You should be ok. Don't go by any cops revving and you should be straight. They've followed me before without ever pulling me over, not only that, I live about 3 blocks from the police station.

It really depends on where you live. Here, they just plug into your OBD2 port and check for errors. But a CEL fix will take care of that problem.
