Hope you guys can make some suggestions, here goes:
Had just driven from Berkshire to Kent and was accelerating up a dual carrageway on half'ish throttle enough to still get a hit on the second turbo but not lots of fuel which is worrying me now. The car for the first time ever missed on the second turbo so I backed off gently cursing. A couple of miles later as the car felt normal gave it WOT more missing more cursing.
Next day decided to do more WOT testing, no missing, holding 1.2 bar lovely but not the normal enjoyable hard hit on the second turbo, still a hit but reduced. Its seems quieter now with less overun. Now very unhappy and worried.
Am gonna change the plugs when I get home Tuesday (Do you think it may be this simple?) do you guys have any idea what else I might have done or what else to check? It sounds perfect when running...but feels almost like I have refitted the first CAT.
Next stop will be to put it in for a service and rectification at a Supra specialist. The most annoying thing is I was made up with the performance of the car in its current tune it felt spot on/amazing for road work.
Thanks in advance,
Darren
