To determine which Peak & Hold you need
- Grab a multi-meter and select Ohms 200
- Touch the positive and negative leads of multi-meter together to measure resistance (record this number...i.e. measured 0.3)
- Then take the positive and negative leads from multi-meter and put on each terminal of the injector. Doesn't matter the order. Record this measurement
- Take the ohms measurement from Step 3 and then subtract the number you got in Step 2 (i.e. Step 3 4.8ohms - Step 2 0.3ohms = Total 4.5ohms)
High Impedance Injectors - Above 7ohms - No Peak and Hold Boxes are needed.
Peak and Hold 2A - 3ohms to 7ohms (Bosch 160lb/hr).
Peak and Hold 4A - Below 3ohms to 1.5ohms.
Peak and Hold 8A - Below 1.5ohms (Billet Atomizer*).
All low impedance Billet Atomizer Injectors manufactured after Nov. 2012 require 8A regardless of measured resistance.
*Billet Atomizer Injectors - Anything prior to serial # C300**** should only use the 4A/1A. This only applies to injectors manufactured prior to Nov. 2012.

Great quality tux for the price
Color: White, Size: XX-Large, Color: White, Size: XX-Large
I was pleasantly surprised with the quality and fit right out of the package. The cloth has a subtle pattern that gives it an upscale look without being flashy, and overall it feels far nicer than I expected at this price.
Jacket:
The jacket has a good weight and thickness, so it feels solid and well-made. Sleeve length was perfect right out of the box, which almost never happens for me. The only fit issue was a bit of snugness in the chest and underarm area, but I have broad shoulders and a larger chest, so that’s not unusual. My dress shirt sleeve length is 36.5", so I went with an XXL instead of my usual XL to make sure the sleeves were long enough. That was the right call, because it’s always easier for a tailor to size something down than to try and make something too small work. Aside from a quick tweak in the chest, this could easily be worn straight out of the package.
Pants:
The pants are noticeably thinner than the jacket and you can kind of see through them, so you’ll want to be mindful when choosing undergarments. That said, the lighter fabric is actually a plus for summer outdoor events or warm indoor venues since it will help keep you cool and comfortable. The flexible waistband made them very comfortable, and the fit in both the waist and length was spot on. For reference, I usually wear 38x32 dress pants and these matched perfectly.
Overall:
The quality is excellent for the cost. Even with a minor tailoring bill, my total cost to own this tux will still be less than renting one for a single event. I couldn’t be happier with the purchase and wouldn’t hesitate to pick up another.
