Vararam codes??
I am planning on installing a Vararam and Powerduct on my 98 stock C5, and I read that this may cause engine error codes?
Does anyone have any input what to watch out for?
Thanks, Titan

Insure you get a nice tight seal. Some cars throw codes due to the increase in flow and the maf being closer. Might as well get a tune. If you don't have a good tuner around I suggest ECS for a mail order tune . They have a huge thread about it and I stand by their work.

NORMALY installing a VARARAM will NOT trip any DTCs....... I have installed three Vararam VB2;'s and none have had any issues... However,,,,,,,,,,you may see a slight drop in fuel mileage. That happens because of the MAF calibration.
Tuning will solve any fuel economey issue as the MAF is normally re-calibrated during the tune. Just installing a Vararam, (IMHO) is not worth a TUNE ($300-$400) If it were me,,,,I would install as many performance enhancing mods as I could and THEN get your tune to get the most out of your MODs.
Some other low buck things that you can do to enhance performance are:
-178 deg T Stat
- Ported Throttle Body
- 97-2000 C5 "Upgrade to a C5 ZO6 intake manifold" 2001 + already has the improved C5Z Manifold!
I've only seen positive results from a VARARAM install.

I have the VR+PD on my 02Z.The PD gave some lean codes but adding the Halltech screen solved the turbulence & codes.That's been over a year ago and no probs since.
IMO,The Halltech screen is worth the $40 and would be a good mod before a tune.

The screen goes in the front of the MAF.I don't know if your MAF has a screen....The 02 Z's came from the facto w/o one.
Have a look here....

Your 98 is suppose to have a screen. Mine had one and I removed it.
As far as i know,,,only 02 and up ZO6 MAFs do not have screens but,,,there MAFs are properly calibrated to operate with out them.
If you remove the screen,,it will still run fine. You may see a closed loop cruising driveability issue and may be a slight loss in fuel economy.

02 had veraram for 5 years no issues. added LT headers, catless, x pipe and billy boat bullets, 160 stat, power duct. only code comes from removing 2 o2 sensors. no tune no issues. if you get a cam then u might want to get throttle body and intake mani also a tune would be good then
