Will Swapping A Turbo Ruin A Tune?

[Deza3000]

Hey guys, i got a little bit of an issue. A few days back i decided to get my car mildly tuned (after some minor modifications) for 98 ron fuel and driveablitiy. Towards the end of the tune, the car was making much more power across the rev range however, the tuner stated it should be much higher provided the amount of boost the car was running. He then checked a few bits a pieces and then noticed the compressor wheel on the turbo was damaged, it had a few pieces missing and looked like it shaved a bit of the turbo housing.

So basically i need a new turbo, however this tune cost me 880 dollars, Seeing as the boost is adjusted via the solenoid, will getting the exact same second hand turbo throw this tune out the window?

If your swapping a stock turbo for another stock turbo, then it wont be too bad.... just not ideal. Of your running anything other than a stock turbo, then yes, your tune will need to be adjusted.

If you replace the turbo another tune should not cost $880. Speak to the tuner and see what he says.

Will you be replacing with the same model turbo? A 'touch-up' tune should cost less than $200 to check for knock, AFR's and so on...

If it's an entirely different snail, then it might be debatable. $880 is steep though.

Yep. One of my mates is getting stung with the 'oh there was a foreseeable problem, but I didn't bother telling you. Come in for another tune for $700'

You'll need another tune if it was really down on power for the amount of boost he was putting in. Think about it... Once you put a new turbo on it will run lean.

you never really got the right tune. So you will definitely need a new tune.

My evaluation car gets different turbochargers fitted every week. Its just a matter of touching up the fuel and ign map, usually take about an hour to do.

^^This. Listen to Stao- he speaks on experience and knows his stuff.

Yea most like be the exact same turbo, only thing different would be the nozzle are going from 9.0t to 9.8t (seeing as i cant find 9.0t anywhere).

If its just an extra couple 100 for the tune up then ill probably do it asap, another 880 then ill just stick with my current setup =='
