bought one of them fleece all lights on boards. just put it in. wish i drove at night more to take advantage of it more. but for 10 bucks figured why not.

also noticed i need a new fog light bulbs, ones dead and the lens housing is wet inside.

That reminds me, I was behind a Colorado today at a stop light and noticed his ds tail light had about 2” of water in it. It was super distracting as I followed him, watching it sloshing around like a fishbowl. I was thinking it would look cool with a goldfish in there.

What do you mean by it “worked” on your old c5 vettes? It’s been shown to make no HP difference via a dyno and by very little temp difference actually measuring IAT’s. There’s been so many never ending threads on this it’s funny. If you want to read one, here.

Well.....thats why I said "infamous TB coolant bypass" , meaning somewhat controversial.
I've been racing since I was about ,OMG, 7 and anything you can do to reduce heat increases power and speed, IMHO.

Take this car for example. It originally came with coolant flowing through the throttle body, made about 360 to the wheels
Now it doesn't have coolant going through the TB and makes about 630 to the wheels....LOL
Granted the engine is larger as is the throttle body. This is a runway car and ANY reduction in powertrain temp directly translates into increased speed.
I live for a 5 degree reduction in temp, any temp....OMG! It can mean the difference between 165 and 171mph.

LS1Tech? OK.....those guys BS and blow shit up all the time over there.
There is no way you can increase the temp in the engine or any component thereof and expect to increase or hold power constant.

LS1Tech? Coincidence.....I originally bought this car from a guy on LS1Tech. He totally misrepresented the car to me when I bought it.
The trans was blown, rear diff was shot and the engine tune was way off leaving about 100whp on the table. It had the right engine parts it just wasn't sorted.
It needed like $15K to sort it out. But now I would say its the fastest NA runway C5 on the west coast....There are a few on the east coast that are faster.

You can't believe everything on the internet, but you can believe that heat is a mortal enemy of power and speed.

Yep, and you won’t decrease the IAT on any LS by doing a TB coolant bypass. Show me the before and after temps. As in actual science, that can’t be attributed to something else or isn’t within test fluctuations. I’ve looked and nobody has been able to prove it. The air flows through that tiny area that’s heated too fast to affect it. But if you want to believe, that’s fine of course. It doesn’t matter if you go to LS1 tech, pt.net or anywhere else- it’s all controversial, can’t be proven consistently enough to be accurate and comes down to what you believe. Now if an entire intake tube like the cheap o aluminum eBay ones are warm it definitely will raise the IAT but not that tiny stream of coolant flowing across the TB.

I don’t think it’s that it necessarily doesn’t have an effect, but that the effect may be too small to measure.
If you started carrying a clean change of pants in your Yukon, it would make it slower, because the vehicle is heavier, but you probably couldn’t measure the difference.
