Subject: Re: AFR's, Did I gain anything...... by Steve40th on 2010/6/12 21:30:44 until you get it re tuned for AFR etc, you arent going to see any gain. If the heads flow better than your last heads, which they should, you wont gain anything till its retuned. Its like putting headers on a car, they are worthless till retuned. Besides, there is a difference between Rockingham from Feb to June. Been there done that ;) |
