Posted in ignition section as I'm praying it isn't rings lol Took it for a drive after warming it up and was driving fine under boost, low and full. Then after about 5 minutes it started making a noise kind of like launch control and a bit like a Subaru. It was very hesitant and wouldn't accelerate or pull hard. Pulled over and checked for smoke out the back, nothing? Revving from idle it shudders and is hesitant before revving normally half way up the rev range. Please tell me it's something simple related to the ignition? Car is running 1 bar on CT9 Mines ECU Uprated plugs, leads Exhaust, FMIC, the usual stuff Thanks Amjad
