Yeah thats the same thing i felt when the canzoomer was in my car and i was actually losing 10 hp.its all in your head i have many bolts on and iam just letting you guys know i lost all my hp gained.my next goal is to find out if i reset the computer will i get it back.

How do you reset the ECU? Can it be done w/o any tools or computers? I think I should do this too as I got my full RB setup in last week and so far on the first tank of gas I was about 130 mi. at half-tank (full AC everyday - normal pedal) Want to see if it will make a difference on the next tank I get this weekend. Thanks.
Never mind - just saw the post above as I posted this.

I was wondering, would the revi intake and ram air duct pkg have any changes on the emissions?
I know there was one person that actually put it on an AT 8, but could any other AT owners who have this system on please give some reviews on to mpg and throttle response.

I check my idle LTFT using canscan unit after I add the RB intake and duct ram. The ecu add like 6-10% of fuel back depends on the ambient temp. When I drive my car, the LTFT drop back to 0%. In other words, if u drive u car in a city with too many stop and go. the gas mileage will not improve alot. I manage to get my gas mileage to 22.5 mpg on pure highway, but 18.5 only w 40% highway + 60% city.

Driving like a grandma only hurts your mileage. I have posted a thread before about driving above 3000 RPMs. In my CANscan logs, it shows that ECU advances ignition to 44 consistently between 3000 - 4000 RPMs. Anything below is a give and take on ignition advance. I used to preach a lot about granny shifting, but the sweet-spot driving has me hooked. The car drives faster in the city and gets better mileage.
And besides, granny driving is for pistons :p
BTW nhk, that's some good info on LTFT. I should try that on my logs. I'll have to sacrifice intake temp for that since I usually run this setup: RPM, MPH, Advance, Intake Temp, Airflow, AFR.

Okay I installed the RB REVi box and RAM cold air intake today. Really easy to do, instructions are excellent and everything came apart nicely....and went back together the same way.
Of course I've had no chance to do anything other than a short test drive. Intake noise is distinctly louder but not anything unacceptable. A low freq noise even at lower rev....like 3500. I was expecting that to show itself around 6000, not 3500. So far I like it. I'll log some reading on the drive to work tomorrow to see if there are any noticeable changes in things like intake temp....

The Professor
When everyone installed their REVi, did they have a small gap (like you can just see part of the hole for the intake in the sheet metal at the bottom of their REVi when they were installing it?
With the bolts tightened, I just couldn't position it to be perfectly over the hole in the sheet metal, it kept riding up as I tightened the bolts.
Anyone else notice this? Did anyone else get theirs to sit perfectly?
