Here is a link to the max ipw rates. You can see in the scan that I posted that I am upwards of 21 - 22 around the 5600+ rpm range, which is pretty damn near max for a stock 36# injector. The reason I am, is because I had to add so much fuel up top to get rid of the 10* of KR that my very restrictive exhaust is causing. Next week when the rockers, headers and dp are in I will obviously be able to re-tune and lower the amount of fuel that I need to keep the KR down, and thus will drop below the 80% high-watermark that I am over now.

Look at #7

Make sense at all?

Ya I follow, I think I've posted refrence to that chart a few times. But the bottem line in your M90 with a 3.25 or 3.3 (in you mods) at 6K engine rpms. Isn't pumping enought air that the stock injectors can't supply fuel . I can't look at any of the exell files. But I have to assume if your IPW are getting that hi you AFR is pretty rich, Just my option. Me and others here have made alot more power than you are, and stocks have been fine up to about the same limit everytime. I don't want to say names but Mr. L has run a 2.8 pulley 319 WHP and 12.8's at 108 on stock inj. Mr. M 300+ WHP 2.6 pulley 12.6's -110 Mr. C 300+WHP 12.6's-110 also on stocks. So somthing isn't making sence then, Hopfully others see whats standing out in the scans.

I am open to any ideas. Someone told me that my fuel presure may be too low as well, and that could be causing those numbers. I don't have a way to measure it so I don't know for sure. I will try and get a few screen caps so you can look at the numbers in the tables.

If others can look at the scan, I would appreciate any input.
