Will i need a different map than the stage 2 map if i use a catless DP? If so where can i get it? Has there been any problems with running catless? I have a perrin short ram, a perrin BOV, cobb AP stage1, and i am thing about getting a catless greddy DP and TC-i catback

 

I run catless stage 2, cobb ap2 & everything runs okay, I think the best thing to do is get a tune

 

i ran it and it ran fine but like ayo said get a tune for best results.
