hello i have just purchased a honda del sol it has a b18 block and a vtech head the vehicle runs and idles good the only problem is when the vehicle hits about6k rpm or about the time vtech kicks in it falls on its face almost as if there is a governor. if i hold the accel pedal to the floor it will accelerate good to 6k rpms then surge if i continue to hold pedal down. the vehicle is equiped with a zex nitrous kit. which i have not used yet. the fuel injectors are RC550 cc. i am unable to scan the vehicle due to lack of cables. im just wondering if theres something people are doing to enrichen fuel with nitrous present and im running real rich under high rpm's or if it could be an ignition problem or possibly a vtech issue turbos max pressure is 7psi it hits 7 psi steadily before power is lost. any ideas would be appreciated.
