For some reason it won't accelerate smoothly at around 2500-3500? It feels like the throttles coming on an off?It boosts smoothly after 3500. I've already made sure there's no boost leaks. Any help would be great...Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...

Slowxr6t Member 560 Member For: 6y 12d Location: New zealand Posted 08/05/21 06:54 AM Share Posted 08/05/21 06:54 AM My reply is only 7 years late to this topic, but I had a similar thing happening and it still does to my car after a fairly large round of mods and a tune. It turns out it was traction control kicking in when it sensed a very small amount of wheelspin. Feels like it's surging and if you watch the boost guage it boosts up then drops down then boosts up etc etc, turns out there's nothing wrong with it. Turn traction control off and go hard, just be careful! This may have been your problem. Link to comment Share on other sites More sharing options...
