Log or have a friend watch block 20 during a 2nd and 3rd gear pull. Look for timing pull. If timing pull is happening, use lemmiwinks or appropriate software to back off the timing a little at a time until block 20 stops showing timing pull. Conversely, log or look at block 32 for fuel trims, if it's adding fuel, look for defective or inadequate fuel pressure regulator, clogged fuel filter or wrong pressure regulator. On my REVO stage 2 I had to back off timing about 3 degrees to keep my timing pull to a minimum as well as run a 4.5bar fuel pressure regulator. Max pull you should see is 5-6 degree's. Preferably 0 degree's, but up to 6 degree's is acceptable.
For further information about logging blocks and oher useful information, please refer to the FAQ at the top of the main forum page as well as the Ross-Tech website.
As for the NO POWER comment, if it's really bad it could be a clogged cat or a defective/dead or dying 02 sensor.[/QUOTE
Thanks for the vital information. I have no cat since stage 2 requirements say you don't need one, so since I have revo tuning will i still get a cel if i have bad o2 sensors? i hope this isn't stupid questions:facepalm:
