just wondering if anyone out there has any experience with an Si reflashed by hondata without any other mods. do you really lose alot of power. all i have is a K&N and hfp axleback. don't really want to get into too much modding, but would like some kind of tune to help as i'm sure it's not an optimized tune from the factory. it just takes so long to get to vtec. i came from a 528whp EG hatch and an evo MR, and my Si is like having turbolag without the turbo. in vtec, it's a fun car, but it just takes so much revving. the 4800 rpm crossover of the hondata sounds appealing.

Check their website but I think they said you need to have a minimum of an intake or you will lose power.

need a intake or header... bc u will lose power at midrange, which is the lowered vtec range (4500-5800)

now is your k&N just a drop in filter, or an intake system? i'm pretty sure you won't lose any power with those bolt-ons. from what i have on my si, injen sri and injen axle-back, the reflash made a lot of power! is the hfp axle back less restrictive than the stock unit?if so, i would recommend go forward with the reflash. good luck
