Real IAT Mod Kia stinger gt 3.3t

These largely mirror my findings as well, although I have a 3.3L G70. The car just feels a lot more responsive at low and medium throttle inputs and I've been surprised at times at how hard the car launches at 50-75% total throttle.

Nice to know im not completely crazy. I was a little hesitant to post my review just due to the fact of "its a 2.0, move along". Haha!

No codes or engine lights or anything? Also as far as the install goes, is there a video or how exactly do you install it? Thanks for being the guy to test it out, I'm excited to try it on mine and see how it reacts?

Install it comes with instructions it's really straightforward. As for engine codes and things like that I've had nothing.

Awesome thank you!

I've had no codes/check engine lights. I used the instructions, but the cable assembly was delivered with some of the connectors plugged into each other. That made it take a little longer to install as I had to determine what plug was supposed to connect to which connector in the car's engine bay.

I did encounter one issue where my engine cover broke when I went to remove it (I suspect the plastic was brittle due to my garage being pretty cold at the time). This isn't a big deal as I'll just run without the engine cover moving forward. I've had one of the manifold spacers mentioned earlier in the discussion in my possession since last spring and this might just be the push to finally get me to install it as I was on the fence over not being able to use the spacer with the engine cover installed.

Damn that sucks, thanks again for testing it out, I definitely wanna buy one.

I have the 1 inch intake manifold spacer and the real IAT harness installed. Who needed engine covers anyway lol

How did you find the install for the spacer kit? I have the 3" upgraded intercooler piping kit from IMR that I suspect might complicate the installation a bit.

There's no install intrusions for the spacer but the spacer/rubber gasket come with pre drilled holes and the mounting hardware (extra long bolts and washers) is provided as well. I have the Stinger GT service manual downloaded on my computer which helps. You'll have to remove the top half of the intake manifold and the spacer will go in-between the parts of the manifold with the black rubber gasket facing upwards.

Thanks a million for the parts breakdown and procedure, that's a huge help.

One thing I'd like to identify from BMS's testing on their dyno (aside from emulating this harness to accomplish the same results) is they tested AFTER install of CPI. I'm no expert by any means but in my mind based on the fact they're introducing atomized fuel into the cold side of the intercooler well before the sensor, any gains even down low that this harness mod provides will be ultimately diminished as a result. Personally I would have preferred to see their testing conducted PRIOR to any sort of pre-throttle plate supplemental fuel or meth injection.

The simple fact is this, there is ABSOLUTELY a felt difference through my butt in how this car drives with and without the harness. I purposely pulled mine out to see if I noticed any changes. TL;DR, it's like flipping a switch in terms of drivability on the street. Dyno results be damned, I will not drive this car without it. Period.

Moving the IAT sensor will affect drivability much more than peak power. A dyno test won't show any affect of this. The giant fan in front of the car with the hood off is kind of important.
Many things can be learned on a dyno. Some can't.

Are you guys also bypassing the throttlebody coolant line while you're at it? I'd expect that individually any of these (coolant bypass, manifold spacer, IAT swap) might have minimal effects, but perhaps done together they'd add up.

I thought about it but, no I didn't bypass the throttle body coolant line.

I will say, since I have a Lap3 1.5+ ECU tune plus all the over stuff. My low end and mid range power band feels very strong.

I have the kit installed for over a week and it is FANTASTIC! More torque than I expected now I am going to clean them and get ready for a road trip. Thanks again for a nice quality harness!

Sweet someone else saw that as well. And i agree 100% on the drivabilty aspect. There have been too many butt dynos and consistent reviews to not believe that there will be upsides to having this harness.

I generally have a lot of respect for Terry as he's been very helpful overall on social media and the forums, but I really don't appreciate how he's shown up in this thread and effectively pissed all over this product. I don't think he had anything whatsoever to gain by doing this as this product isn't in any way competing vs his own products. In fact if anything I think the JB4 and this harness are likely synergistic in nature.

I agree. Now i have the fmic and pedal tuner from BMS but no jb4. That said anytime ive been asked about them ive always brought up the tech support. Lots of my friends run them and ive seen the support given when issues arise. That alone speaks volumes. Ill stop there but yes no reason to beat up on this

I did the coolant bypass a while back. No issues, but no differences noted whatsoever.
