Well...I have had it for a day, I seriously didnt really feel any different, or i am thinking i need to reset the ecu and give it sometimes?

reset ecu won't do much imho. over time it will just get back to normal. maybe just some similar effects as gnd kits i guess

unless you are running a high power system or have shortages already.... you wont notice much difference w/ any voltage system. if you do notice any it will be very minimal.

I bought it was cheap, not sure if it does anything but i'm sure it doesn't hurt anything either so why not.....I'll let you guys know if i feel any difference with it !!!

Let me know how it works. Did you ever order the grounding kit?

Whats up buddy, how are you i didn't but i plan too soon, whats with the headers..........I'll let you know how it works for me........

JBrady is test fitting a 430 Y pipe on a 400 soon to see if his headers will bolt on if not JPI is making a set of headers for the GS430 in stainless. So we will know soon whats going on.

I have the full MR system for my 03 GS3 and i didnt notice much in torque or power response but i did notice a signifcant increase in gas mileage. Given Ive only had the car for less than 2000 miles, I fill up using CA 91 Octane at close to 3 bucks a gallon, probably why I went GS3 over a 430. My first 2 fillups, with normal highway and city driving, I got about 320-335 miles on a full tank, of course I didnt run it till tank completely emptied, but to where the light goes on. After installing the Sun System, I was able to get 355 on the fist tank and Im on my second tank now. Ive got about half a tank left and its at about 198 miles, so Im thinking maybe I can get about 350+ on this tank as well. Sure its not a lot more, but enough to warrant spending an one time $250 on and saving gas overtime. In N. Ca where 91 is like $2.89 a gallon, its worth it.

*On a side not, my buddy's Infiniti G20 with the same Sun System, drove from SF to Covina on one tank. Yea its a 4 banger, but 420 miles!! on a G20 modified with intake is pretty damn good
