I am getting a AP next week and I am wondering if I should get TP stg1 or just use the OTS Stg1? I have a DP @ home and plan on putting it on in Feb or so, and plan on TP Stg2 at that point. The thing I am worried about is I have a AEM intake now w/o a tune, and have a CBE but that is it. The reason I ask is because I am going through some training and have to drive home (2100 miles), and want to reflash it prior to the trip back. Should I spend the $70 for the TP Stg1 for a few months or will my car be ok until I put the dp on and go TP Stg2 @ that time? I really don't want to spend $140 when I can spend $70, but I don't want to ruin my car by not getting my AFR right. Basically wondering if my AFR will be ok until I get the DP on? Word!
