Josh, you can meet me over at Mainstream in a few weeks for some more tuning. I will show you the potential of the IPS K2s. :up:edo said:That was a K20A2 that had bad ring seal. It was down on power when he first tuned the N2's last December. The test is valid since he did not re-ring his motor prior to fitting the IPS-K2's, but is not a good indication of potential power for either sets of cams.
