This might sound like a silly question, but was wondering if I replace my Perrin Turboback with a different TBE (single exit), would I need a new tune. Or a turboback is just a turboback? Thanks guys.

 

it would be wise to stick it on the dyno to double check your AFR's

 

Thanks for the advice, I might as well since Ivey is close to me anyhow.

 

I would contact Ivey and see if he can do a quick check with the new TBE - and maybe make some small modifications.

Since he tuned you in the first place you might find the above will only be a fraction of the full tune...

 

Very good point, and I believe that's what I will do. Thank you for the great advice!

 

Unless the new system flows substantially different than the old one I don't think it's an issue but I would double check the AFR's. You should have a wideband in the car just in case anyway.

 

Also good advice, thank you. I did plan on getting a wideband in the near future.
