LPE supposedly has some +90's coming out...not sure how those will be to tune.
I prefer to fuel the engine DI only, but with the price increases on DI fueling, PI starts to make a lot more sense.

For sure, the cost now for pi stuff seems to be quite a bit cheaper than upgrading di and you get more fuel. Adjusting the rail pressure and pulse widths at idle was something I saw from a Greg Banish video. Wanted to see other people's opinions about it. Wouldn't be dropping rail pressure too low or pulse widths too high, just finding the sweet spot Radz was referring too for a nice clean burn and smooth idle.
