Hey I recently ordered RK tune as well. I am wondering what does ur "Stage 1" mean? Like you don't have a downpipes in your car? Is the HP lower for your car since you are on stage 1(Just tune, no dp)? Also how long did it take for RK to send you your file? I have been waiting for 5 business days...
