Gday did the EGR mod last weekend.Fitted drivers side,removed batt for ease of access,simple half hour job.Totally transformed car,where it was sometimes dangerous pulling out in front of traffic due to massive turbo lag,it now drives just like a normal car,no getting revs up & slipping clutch,it just pulls.Fitted my 265 75r16s today,noticed no change in drivability off the mark,but better on fwy.Best mod I have done by far,havnt found any extra power but just an around better car,wont be putting it into low range to pull the boat out this summer.Hugh
