I have a 2010 GSR, and it has happened to me a few times when I take the car out on first gear the car will start hesitating when boosting, full throttle.. It usually does it like the first run after I turn it on, but then if I accelerate again it responds normally.

Anyone has had this issue before, Any suggestions??

Only Mod I have is CNT 3" Cat Back Exhaust

 

Check the FPR hose. That can come loose and cause havoc. Mine and many others zip tie the hose. You might make sure you have the most up to date fuel pump relay as well.

 

Car isn't warmed up and turbo isn't either. Let the car warm up for 5 mins or so. Don't ever boost before your car is warmed up, you'll start having more issues if you keep doing that.

 

Thats true ^ in warm weather u don't need to let it idle long but 1-2 minutes should be fine. Than you just take it easy for a minute or two and should be having no issues that you described.

 

Also, remember you have mivec which if not warmed up won't work properly either.

 

well if it happened repeatedly, id say clutch... but it doesnt... soo no idea

 

I think he isn't letting it warm up properly like stated above.

^^My first thought was maybe the clutch slipping too when I read the title..
