This was a long time ago so I may be wrong.. But when I got mine put in I specifically asked them to chuck it on the dyno for that reason.. If your gettin em done at a shop, get them to run it up just to be sure... Edited 03/11/10 06:55 AM by MiKa Link to comment Share on other sites More sharing options...

Never had an issue. But with these cars stranger things have happened. Link to comment Share on other sites More sharing options...

PSI40L Member 175 Member For: 22y 5d Posted 12/12/10 03:38 PM Share Posted 12/12/10 03:38 PM (edited) depends what was happening at the time of problem if motor was showing valve float on the dyno then I would suggest yes just to be safe if it hadnt been backed off.A bouncing spring will give a varied afr...Not on something that's standard though.last thing you want is a lean mixture up top Edited 12/12/10 03:47 PM by PSI40L Link to comment Share on other sites More sharing options...

Unless you are stuffing around with AF ratios etc it wont make any differences. Link to comment Share on other sites More sharing options...
