Car was running fine the past few weeks...Last night i decided to stretch it a little and she started acting funny....Whenever Vtec comes on and boost kicks in the car seems to be breaking up...It will run fine then out of nowhere it will almost feel like it shut off then come back on...I was playing around with the timing and fuel pressure regulator..maybe a F*ed something up?...and a friend of mine drove it last night too before this started happening and missed 3rd gear...Do you think he could have over reved it?...Im running a boosted b17/b16 head with Hondata S200..450 injectors etc...
