vararam install issues
well i had to sell my halltech a few weeks ago. So i just replaced it with a vararam. The install was not to bad and it seems to fit okay. I have put maybe 200 miles on my car since the install. NOW i am getting a check engine light with codes 0171/0174. These are codes that say lean bank 1 and 2. Does this mean that the vararam has leaned out my a/f ratio to the point i need a tune? Or could this be i just need to make sure i dont have a air leak somewhere? I have cleared the codes out twice now and as soon as i drive the car, turn it off and then restart it the light/codes come back.

I have a Vararam but have yet to install it... I wondered about this issue myself. A lot of VR sellers say a tune isn't necessary, but... well, these things tend to happen.
Aside from getting a tune to straighten out any errant trouble codes, would the tune also add more power above and beyond the Vararam (completely stock otherwise?) About how much?

had some home repairs i had to make so to offset the cost i sold the halltech kit.
I pulled fuses 16/23 and let the engine relearn the idle. I drove the car a lot today and did not get any codes/check engine lights. I still have a surging/bucking (light but there) esp in higher gears/low rpm/very light throttle. I am hoping this goes away or can be fixed with a tune.

Disconnect the battery and do a relearn. You can do 3 heatups to
opp. temp and let cool back down. Or take it out and drive it up
to around 200 miles varing the speed and it should adjust its self.
I have had 3 vararams and this has worked everytime. The only
problem I had on my 04 Z was a low speed surge. I took the descreened
MAF out and put in a screened one and solved that problem.

Some tuners won't charge you a second time to retune. Ask the shop you are going to and see what they will do for you. If you've checked for leaks and all is well their I would prefer to get the car to run right now to stop some of the problems you describe. A tune will solve it.

I have had my vararam and bridge installed on my 04 Z for about 6 months now and my check engine light comes on periodically. I am going to get it tuned, but for the time being, I just go into the diagnostics and clear the codes myself and that usually takes care of the light for a few months. I do encounter the lowspeed surge, but hope that will stop after my tune. None of the issues are a problem for me considering the increase in performance I got. Just my opinion

I have an 02 Z06 and recently installed the VR and the new air bridge - I get the same codes almost every time the computer goes into closed loop at warmup. If I clear them out, they do not re-appear the entire time the car is running. I have also checked all of the connections a couple of times, disconnected the battery, etc, so it's looking like I need a tune also.

Sucks that i have to get a tune for a cai. Esp when i could not even feel a difference between the halltech venom and the vararam on the street. At this point i wish i had just bought another venom kit for my car.
