Default Dahlback is in...opinion and some questions

I love this chip, I dont have alot to compare it to but i did beat an RSX type S. It peaks at almost 20 psi when floored , drops to 17 by 4200, then 15 around 5500, and holds 12-13 to 6600 where i shift, dont see any real need to rev it higher than that.

My CEL came back on, 1136 is the OBDII code, i had it once before when my N75 valve **** out. the car surges at WOT below 2800 rpm or so. All turbo inlet, outlet and IC tubes are tight, new FPR and DV vaccum lines. I ahve an EVO billet DV and a new turbo. I tested my N75 w/ an ohm meter and got around 30 ohms, when i researched that seemed right. It is a 1997, maybe i need to update to a newer MAF b/c im maxing the older style one out? Do FPR go bad? I dont know when my fuel filter was last changed, deff not within the last 25,000 miles, im doing that today. any other possibilities?

Default Strong Suggestion...

FORGE VALVE on Spring 2 it will smooth out the power and keep the Fail Safe codes at bay.

Been there had it happen with APR ****ware

Default The ndbw also had the smaller 240cc injectors.

So I bet those injectors are just screaming at that boost level.

Default Could be.. but...

I ran with the second Forge Spring and it was great..smooth but just a bit off top end power. (2.7T) Then the day I switched to spring 1 I had a bad launch, the clutch slipped the eRPMs when to 7 grand, I went in to safe modde. and then heard the turbo lady sing.....

So... I like Forge with spring 2...for you Spring 3 may be needed.
