Does anyone have proof that a 190FP doesn't need a regulator?

Does anyone have proof that a 190FP doesn't need a regulator? Did you actually take a FP reading? Fuel trims change after pump install?

I don't wanna loose any kind of off boost performance, due to a bigger FP increaseing FP and casing a rich fuel mixture with off boost performance. Thanks.

well i have one in now with the t-25 and i havent noticed any differences power or fuel mileage wise.. i also dont run a fpr..

Are you rewired or not?

I'm thinking about 190 nonrewired for my EvoIII.

I heard about some one dropping in a 255 and it was ok...but when he rewired it his low end was really sluggish.

I have a rewired 190 in my car, still on the T25 and other than the noise of the pump I didnt notice anything.

I had a rewired 190 with a 16g and I didn't use a regulator. No problems at all with it that way and fuel trims were fine.

Dang are the 190s as loud as the 255? I heard one whining a few few weeks ago and it was pretty loud

My 190 is only audible ar Idle and you really have to listen for it.

My non-rewired 190 was plenty for my Evo 3 16g at 20psi.

The 190l whinebro doesn't need a adjustable fpr.

You should have the means to alter low throttle corrections with your dsmlink if necessary.

i have a 255 on my 2g. 550's, afc, fmic , bla bla bla. works FINE without afpr. boostin 18-20 psi all day.

No, I can only control open loop fuel delivery. All timing adjustments are for both open and closed loop operation.

Yeah open loop. Thats where your fuel trims come into play. Do you mean you can only control fuel on closed loop( full throttle) ?
I'll admit I never played with the dsmlink so I may be wrong here.

You have it backwards. Open loop is when the computer doesn't look at the o2 sensor to control fuel delivery. ie when high loads/throttle and higher RPMs
