Overview:

Take control of your GM Gen V LT1, L83, or L86 engine with Terminator X! Do not settle for a factory ECU with a cumbersome tuning interface when you can have complete control of your engine, self-learning fuel strategies and the proven, race-winning technology of Holley EFI at a budget-friendly price!

The inputs and outputs are ideal for electric fans, boost control solenoids, progressive nitrous control, and much more.

The 3.5" touch screen LCD handheld contains an easy to use calibration wizard as well as tuning and gauge display functions.

Whether you are building, an LT swapped budget beater or a boosted racecar, Terminator X has the features and technology you need at a price that will not break the bank!

just buy them
Size: 300 Count (Pack of 1)
Look.. They are paper plates. Are they thin? yes; use two of them, they are cheap enough. If you want "sturdy" to hold your spaghetti or thanksgiving dinner, then use a regular plate and get out of the review section. We use for pizza, sandwiches, hotdogs normal paper plates foods to avoid washing dishes 17times day. If my kids use 25 in one day. so what; each plate cost less than a penny. Bought 300ct in Feb 2025. It's April 2025 and I'm getting ready to place a 2nd order.

Low Quality, High Quantity, But Definitely Overpriced
Size: 500 Count (Pack of 1), Size: 500 Count (Pack of 1)
When did low quality paper plates start costing so much? Yes, you get 500, but these are very thin and I tend to use 2 or 3 at a time, especially when they stick and I don’t want to deal with ripping them apart. These are just ok. Nothing quality about these plates but they do what I need when I use those paper plate holders to keep them supported.

NICE for soups!
Style: 34 Ounces, Size: 34 Count
We try to keep these in the house. They are REALLY nicely sized and work great for soups. They are AWESOME for soups and the only disposable plates I feel comfy using for large stews and such. Makes cleaning easy because I don't HAVE TO CLEAN! They are a bit more expensive than otherd disposable plates, but they are worth it. Pretty heavy duty plates that are thick and great for heavier foods. <3
