electronic upgrades

[hep2]

Hi, I go by Rick or hep2. I'm new to this forum, i've owned my xd for almost 2 years and I love it.I got the whole trd susspension package and I realy like the way it handles. Great mpg with the 5 speed manual and nothing special on the rest of the car except maby the 16" alloy wheels although I was dis appointed to find out the were painted rather than polished,oh well less work to maintain. I got the car to transport my model aircraft to the feild and it makes a great aircraft carrier it also doubles as a comuter. the main thing I would realy like to change about my xd is the acceleration it seems to be lacking a bit in that department and now that the power train warrenty is done it's time to mod.I am most interested in bolt on electronic upgrades has any body tried the SLR chips? do throttle rate changing devices change porformance or just throttle rate?
