i will be installing my heads that have 1.7 rr on them. they are ported gt40s. my question is will the computer have a **** fit on my if i dont get a tune. (i wont have the $$$ for awhile). i know the steeda 19 is supposed to be a good cam for the 94/95 and not need a tune, but will that change with the 1.7rr? btw my springs will be able to handle it. thanks
