Guys using TunerPro RT

I put in some 950cc injectors and a supra fuel pump. Now I cant get it to run right. I added 310 to my deadtimes and typed 950 into my injector compensation.

with the injector compensationset at 950cc it will rev fine till 5,000, then it acts like a stutterbox but with no boost. It also wont idle with the compensation set at 950. So, I set the compensation back to 450. It idles ( a lil rough) but won't rev at all.

The car is a 92 GSX that is all stock except for the Tunerpro Rt, Ostrich, and Fuel pump. It ran fine prior to the injectors. I tested for boost leaks and got nothing.
I'll post my bin and xdf do you guys see anything? any insight would be great.

Perhaps that IS a studderbox? Where did you get your original bin file? If you did the typical TunerPro RT setup, you probably got the bin which already has a studderbox set up.

I also have 950ccs but for some reason I will be too lean if I set the compensation value at 950. Right now it's around 800 and sorta OK. Also which xdf file are you using? We can't really look at the bin without the right xdf file.

The xdf is the same as the bin.
I found out what the problem with boost was, my actuator arm wasn't hooked up.:D What a newb huh?

she boosts okay if I roll into it, if I stomp it it's HELLA rich.

Do you have an adjustable fuel pressure regulator and can you monitor your fuel pressure? If you don't, your fuel pressure is probably sky high at idle and just keeps going up from there.
