Have a 06 IX with 49k miles. Fully bolted on / 272 cams / 385 / 30psi stock turbo currently.

I am going to be installing an FP red setup and was hoping it'll be okay to drive ~2 hours without a tune as long as I do my best to not hit boost

 

Youll be fine. Done it a few times. Stay out of boost & run in vacuum & all should be OK

 

Awesome! Thanks

 

If you're on MAF, it'll be OK. If you're on speed density, it probably won't run well enough to drive.

 

Yeah MAF you are fine. If SD I wouldn't do it. Your tuner can't send you a base map?

 

I'm still on MAF. And I'm not sure. Wouldn't I need a tactrix cable if he were to try and do that?

 

You're fine on maf or SD given the only thing you changed is turbo.....provided you completely stay out of boost! In the vacuum, idle and cruise range it's mostly closed loop and the timing map largely doesn't change much. Whole different story in boost where even for the same psi different turbos need different timing and fuel.

As a general note, maf does awesome at compensating for literally anything short of new injectors in idle/cruise. SD is more finicky and if you do something like change cams it definitely needs a retune.

 

yes, like allthese knowledgable gentlemen said, you will be A-OKAY have fun with the new turbo

 

I did the same with mine no booooost and your good. PS have the same setup and love it. What injectors r u going to be running?

 

Stay out of boost. Also have had to do this many a time

 

Thanks fellas

Thanks. I have 1200cc Precision injectors. Along with the AEM 320lph pump. Should be enough fuel right?

 

You may run into fuel limits. The AEM 320 has been shown to not really flow much more than a Walbro 255. Injectors will be at the limit as well, I'm guessing around 90% IDC by the time you're done.

 

Well we will see how it goes! Worst case we'll keep the boost down until I get larger injectors and a double pumper or something.

 

Changing a turbo is a huge change in airflow, just like cams. SD will not run well, if its even drivable, without changes to the ROM. I know this because I've done it, my car barely ran when I went form the stock turbo to the red. Required changes to injector scaling and RPM VE, as well as portions of the fuel table to even be able drive it somewhat reasonably.


On MAF he'll be fine.

 

^ I can't say I've had that problem. I've put cars on SD tunes with similar cams/injectors/intake/TB/displacement but different turbos and they would start up and drive in closed loop without too much issue. Turbos effect on VE really comes into play when they start adding serious airflow to the engine. Only matters around 0psi and above. Which admittedly most people run into if they are not careful. If you watch your boost/vacuum gauge you can drive around on it. Disconnect your uicp and try next time.
