It's pretty remarkable what an ECU tune can do. I've installed a cold air intake, gutted all 3 cats, installed a high-performance muffler, throttle body bypass, etc, etc. I've probably spent 30 hours crawling around under the car, replacing this, adjusting that...and then Stas (Stayer) comes...

Warning: Do NOT do this mod. My Engine Coolant Temperature Sensor blew and my car went into limp mode at extremely high temps. and would not start. I almost had to have it towed but luckily there was an auto store nearby where I was able to plant the car under a tree. I had to pay $170 for a...

Most of my car is still stock, I work basically a minimum wage job and go to school, so she's a work in progress. Got her at 71000miles I'm coming up on 91000 in about a year. I've done aux cord install, dipped the wheels, painted part of the interior brush metal color (work in progress)...

Hey guys, I have a 2009 Eclipse GS that I have kept stock for the 5 years that I have owned it with intention to eventually trade it off. I only have around 41k miles on it so far. Ive come to the conclusion that I probably wont be trading it any time soon so I am tempted to start modding it...

First day on the site and its definitely been alot of help. First things first. Im looking for the best place to buy the throttle body spacer for my 2011 Eclipse GS.

So, I went to the drag strip with a bunch of guys in our local facebook car enthusiasts group.. 1/8th mile and by god was I thoroughly impressed!! First race was a 07 gt mustang.. I won, ran a 9.9... I was shocked as was everyone else... Needless to say I am now thirsty for more... I wanna do...

06' GS I've got gutted stock "Headers", Throttle body bypass, Injen CAI, Full catback exhaust, Intake Resonator delete. Are there any other small mods like the resonator delete or bypass I can do? I'm saving up for some other mods like lowering springs, underdrive pulley and strut bar so money...

I Was out yesterday checking out some of my fishing spots and, looking to get some good pictures of nature and of course some of the Eclipse. Well I either pass or drive over this tunnel once a week. So I thought I'd set the camera in the tunnel and make a quick pass mostly for the sound of it...

For the TB Bypass, everyone seems to be taking off the TB then reconnecting the two hoses with the barb, but do you have to take off the TB? I think I can just fit my hands under there and take off the hoses and reconnect them under the intake. Is that fine? or is there a reason for taking off...

If anyone could take the time to write me a list of simple diy home mods? like the throttle body bypass and whatnot, i have automotive experience so not much is limited.

since this is such a simple mod why not?? but my question is.. i know the reason its there is to prevent freezing in cold temps.. i live in wv and we get some pretty harsh weather in the winter, is it safe to do this despite our below freezing temps in the winter??? :confused:

So I searched and didn't really find anything...I did the TB bypass yesterday drove the car hard no leaks...drove it to work this morning and it starts leaking. Took it to a shop, and they fixed it and some how it started leaking again. Took it back and that spliced it, and retightened the...

Okay so I know everyone says if you mess this up, you’re an idiot. So I’ll take the hits for some knowledge gain. Basically I did the TB bypass according to Chaos’s TB Bypass write-up. Utilizing the 5/16 ID Barbed Coupler (which I couldn’t find anywhere, so I connected two one-way barbed ends...

So I saw the DIY thread of how to bypass the throttle body, what exactly will this do for your car? Better throttle response? HP? Torque? Any help is much appreciated :)
