Default Question for the LPT guys.

What is the max boost i can run on a 13G with an MBC?

Thanks

On the 13g you can run 15PSI. Now this is at the end of it effeincy range. Meaning 15PSI may be too much for your little turbo.

With that said 10-12 PSI will be good and you can run this all day long with no issues.

I believe on the stock ECU fuel cutoff is at 15PSI.

With that said I'd highly recommend spending the cash and getting an ECU upgrade rather then going with the MBC. While many people have used and will continue to use a MBC to raise their boost levels it isn't the safest to use. If you don't have a boost gauge that can read 25 In Hg and 25 PSI then get one before you hook your MBC up. See what your running stock and then with the MBC hooked up. Even if you go with the ECU upgrade get the boost gauge and have it installed before you get the ECU upgrade done.

- IPD USA
- RICA
**These are the two best tuners on the Volvo market.** **Also cost the most, but well worth it.**

- Inmotion (If they are still in business.)
- SpeedTuning USA
- Upsolute
**These are three tuners on the market for us Volvo guys and gals as well.** They do less research and development into their ECU upgrades and while they cost significantly less you get what you pay for. They work, I have a SpeedTuning USA ECU upgrade. It works! I run RICH and the customer service from OLIVER is crap. I only did it because of a groupbuy a long time ago. Waste of money IMO and I would and should have saved for the IPD USA and or RICA upgrade.**

ya, i know about all that, and ist just for now im going to use a MBC, later i intend to swap tubo/ECU (and maybe other) so i just want to boost at 12 for now, so i can boost safetly at 15 later..

so 15PSI is the limit of turbo + ECU thanks, thats what i needed to know.. also i will be installing a boost guage before anything... (i dont even have the crap one in the cluster)

thanks alot.

Ididn't have one (boost Gauge) on my dash, and tech helped me with it. It actually is super easy. Def. get one to keep an eye out for overboosting! I run a Speedtune ecu tune I bought off another member on Volvospeed and am happy with it.

If I were you I would run a MBC (obviously a quality one), but not just to raise boost but to control it.
