[06r/cviper]

HI im new to this form and was thinking about getting the d c stage 2 for my my r/c. I was wondering about how many tenths would that help out ? I ran a 12.89 with just the volant ram air cold intake. I only had my truck for a month and loving it. I bought it from woodhouse cheap but any way would that be a good second mod? keep in mine taht the 12.89 was a cold past the temp at the track was 52 with a little tailwind lol
