Clean fuel injectors are always good. Not only from a performance standpoint, but also for a keep from burning a hole through my engine one. Over time, or even out of the box, your injectors can get clogged and are flowing less, dripping, or even having a very poor spray pattern. If they get too restricted you can run lean and then melt things. Before you do any modifications raising boost, cleaning/balancing your injectors should be done. Because I plan to sit around 12PSI I decided to stay with my stock injectors. So I got an extra set, to avoid down time, though it is very short, and had them sent to RC Eng to be cleaned and balanced. The cost is around $135.60 and as a SoCal Supra's member I got 10% off.
Before Cleaning:
| Inj | CC/min | Pattern |
| 1 | 435.0 | Fair |
| 2 | 442.0 | Dripping |
| 3 | 451.0 | Dripping |
| 4 | 440.0 | Good |
| 5 | 446.0 | Good |
| 6 | 447.0 | Good |
| System Balance: 3.7% | ||
Dripping is no good, but these aren't the ones in my car. It will make me feel better when I do the swap though.
After Cleaning:
| Inj | CC/min | Pattern |
| 1 | 448.0 | Excellent |
| 2 | 449.0 | Excellent |
| 3 | 450.0 | Excellent |
| 4 | 448.0 | Excellent |
| 5 | 450.0 | Excellent |
| 6 | 450.0 | Excellent |
| System Balance: 0.4% | ||
Much better. These should give me more power, well give me power back, because of a better combustion, and give me confidence to raise the boost.
