my mods simply zzp s2, his mods i/h/e and flashpro basically hp tuners for a si just better (he can add 2step and did) lol. well when he first got it, he was a noob with it did just testing and tuning all street tune of course. we did a roll and i would get him by 1-2 cars... on our way back from a jersey meet we ended up in mexico and did a 45 roll, he said he did some more tuning and figured some stuff out so he wanted to try again. 1/2/3 beep with me shifting at 6800 on a full tank and him on straight up EMPTY lol. surprisingly he stayed a half car behind. we took it up to 120 mph. i give him mad props with his tuning. its excellent. still a win for me. i havent ran him from a dig yet with his 2step but believe me i will.

 

Nice. Those civics respond very well to boltons
