Ive got a 93 hatch, gsr, garret t60, ext. wastegate, 450cc dsm inj., walbrol 255, aem rail and regulator. Car was originally tuned at 12 psi using chrome. Lowered boost to 9psi and had it retuned as a base map. It has been through 9 programs now, and it is bounceing off rev limiter at 4800. It only does this in my car, others its fine. Open too any suggestions no matter how dumb, as long as they dont say go back to the shop. Its a long *** drive. Please help.

 

its CROME and if there is no codes or nothing else changed then its obviously a bad burn.

 

do you have any shorts in wiring? also does crome have a 2 step??

 

Crome has a two step but it is controlled by the VSS. Unless his speedo isn't working, that can't be it.

I would think bad burn as well.

 

yea i would disable any 2 steps. If the speed sensor doesn't work then that will give you an early rev limit.

 

Thank you. My VSS lights kicks on and off. THat must be the fuel cut. Makes sense. Once again, THANK YOU.
