The talon is running good. Tuning is where it`s at now. My boost creep is under control for the most part the AVCR finally went into self learning mode and seems to be working better but at WOT in 3rd gear I get fuel cut. That is at about 18 psi and around 4800 to 5200 rpms. I know I will have to start upgrading my injectors and ecus stuff at some point but do you guys think the injectors (stock) or my plugs might be causing any of my problems? Also I am running a ported 14b turbo.

Injectors do not cause fuel cut. You are overrunning the MAF currently at 18psi. You will need an Eprom ECU with the proper programming to fully eliminate fuel cut from the equation (the chip burned will halve the MAF value reading and remultiply it in the ECU, somehow it bypasses the fuel safety cutoff). Injectors would be a nice addition along with it as well since I'm sure you're already overrunning the stockers.
If you plan on keeping the 14B: 550cc injectorts (at least) Eprom w/ chip burned for injectors and fuel cut elim. If you want to go to an EVO III 16G since it seems to be popular: 650cc injectors (at least) Eprom w/ chip burned for injectors and fuel cut elim. Correct fuel injector selection is critical. Always go bigger than what you need. You can always take more fuel out but at a certain point you hit the limit of the injectors and you can't add any more fuel. 80%Duty Cycle is the suggested maximum for any fuel injector. You're probably running about 100-110% currently on the stockers. -------------------- "I hear he tunes the space shuttle also...and that thing is fast"
