Fernando... a good DCX mechanic could have ironed out the problems you had with your SRT-4. More than likely, your porting of the stock turbo and exhaust manifold caused problems with Stage 2/toys. Hope you had a wideband air fuel gauge to help figure it out. I got the Stage 3/toys option for good daily drivability and a friend/DCX tech set me all up... goes like a banshee with it's *** on fire, especially in dial-a-boost 1 to 3 settings.

I have an '05 SRT-4 with a lot of the same mods, except after watching all the 50 trim guys run into daily driver problems with fuel and boost management, I opted just to go Stage 3/toys... Love every minute of it.
Ya gotta do the suspension first on those Neons though. (Hotchkiss sways, frame brace, S3 coilovers, strut tower bars, rear control arms).

We are a two SRT family... Highly modified SRT-4 and a stocker SRT-6 coupe in the same color as yours. I'm not messing with the Crossfire. Too expensive to fix if you take it out of warranty. Parts alone will eat you alive. Sure is a blast to drive around corners though.
