I have one of these ebay kits which will go into a 2008 Avalanche. Any recommendations on where to get a tune for it? The kits did NOT include tunes. Other sites and threads I've found are 8-10 years old.

Thanks.

 

Contact a local performance shop is what I would do. Or find someone in your area that knows what they are doing.

I don't think I've ever seen a pre-made Roush Supercharger tune before. It's not like Maggy kits that can come with a tune.

Make sure you have the correct supporting parts to go along with the supercharger. Like fuel pump if you need it, larger injectors, 2 bar MAP sensor. Then pray for the transmission.

If I was tuning it I would be asking what injectors it had, what map sensor and all that stuff.

 

Thanks.

Transmission is why I've been hesitant. 2008 tranny not too strong.

 

Your trans is going to hate you...
