Tune after Converter install?

I'm putting in a Vig 3200 soon, will I need a tune immediately?

yes you will need a tune, IMO the car ran worse after the converter install than the cam untuned

No not immediatly.... My brother has a truck with a 2600 in it, and has been running it untuned for around 4 months.... You will get better performance from a tune though!!

With the 3200 you might have to have your idle reset through a tune. It isn't uncommon for the engine to die when the trans is put into gear. Good luck, Vince.

When I had my Vig3200 installed (stock internals) I had a basic tune for shift points, fans, etc. I took it to the dealership for some warranty work and they flashed my pcm. Afterwards, when driving the car felt horrible. Would always hit the rev limiter during the 1-2 shift and seemed like it would cut power when upshifting (torqe management kicking in?).

With that being said, get the tune. At the time mine cost 100, seems like most places nowadays charge around 150 for that type of tune.

I've been running mine with no tune for 8 months with no major problems. It will hit the rev limiter on the 2-3 shift, but I can live with that for years to come if I want.
