Clear enough, just trying to help the guy out. When someone has a problem and they used a reputable tuner, you start looking for what is missing or what doesn't belong and trying to figure out how it may be impacting the numbers.

Like I said, the oversized injectors caught my eye and I thought it was possible he had been running them and dumping unburnt fuel through his engine. His compression readings were even, but 270 is normal according to the Helms nominal spec for ITR/GSR. At 220 he's about 50 psi short and it could be worse, depending on how good his compression gauge is. He doesn't say what pistons he's runnig but I assumed ITR. He does say the head was milled, so he should be seeing some minor increase in compression over the spec.
Raw fuel continually dumped into the cylinders washes away the protective oil film and causes premature wear and blow-by. He asked if anyone had any ideas. I responded, which led to the discussion about selecting proper injector size.

Meanwhile, the injector sizing chart you posted illustrates well what I was saying should be followed when choosing injectors. Thanks for posting it up.

You have made it clear you routinely advise people to ignore that chart for the reasons you explained. To each his own.
