Re: gsx cutting out?
Do you have a CEL? Maybe you should wait and put your speed sensor in and see if that helps.

Re: gsx cutting out?
That shouldn't be heating anything. Does the car rev past 4.5k when driving it easier. Have you checked for boost leaks? What are you using to control those injectors?

Re: gsx cutting out?
Im talking engine management. You cant just throw in big injectors and expect the stock ECU to control them properly.

Re: gsx cutting out?
Sounds like a boost leak to me. Do a boost leak test. Even if its not your problem its a good thing to check.

Re: gsx cutting out?
Its possible. I dont know if the stock ECU uses it for anything of not. Does the car rev past 4500rpms if you drive easy?

Re: gsx cutting out?
What type of plugs and wires?
What are the plugs gapped to? What does link show for A/F through the logs? How is your fuel set up in Link?
