A custom tune is mandatory with that set up. You’ll need more boost on the lower gears for those turbos to even start spinning good.
It sounds like you have everything planned out so the question is how did your shop drop the ball on a custom tune? Respectfully. Nice set up though. Did you also upgrade your driveshaft, rods, Pistons and bearings? |

What actual 'custom' tune you need will be determined by a tune expert over there, just have to look for one that is knowledgable with this.

Thanks for the reply

My shop tell me that i need new tune but he can't do it because he is not a tuner So the code thrown is most likely related to upgraded turbos and no tune ? What power can i expect from that setup ? |

Here’s an example, I’m running a mild BPM stage 2 tune, MSR intakes and Fabworx catless downpipes. I’m sitting on roughly 705 HP with 675 TQ.
All this was well calculated and mapped out. I’ve been running this same set up for about 90k miles. I could have easily gotten another 40-60 more HP and TQ out of it but at what cost? As I said in my previous post, you’ve spent the bread to have a well built machine. Trying to squeeze all the juice out will ultimately put you into the same boat as many others who’ve tried to push this platform to the very limits. If I were you (and I am you), I would keep your HP below 750 and the TQ below 700. Find a happy spot for those hybrid turbos and enjoy the hell of it (occasionally). I also wouldn’t spend a lot of time punching it from a dig. |
