Kay...time for some good news.
Turns out I was sent low impedance injectors, not steamed @ SP even though it cost me a few grand when the GE went lean, honest mistake and Lar / Garry / Ivan are still the best in my book. TT resistor pack will be going in next week (Scott, what can I say bro
) and we can finally tune for boost.

Were you guys monitoring A/Fs with a wideband when the piston departed the vehicle? Just curious... Wrong injectors, you'd think they would malfunction in a linear manner... Perhaps the ECU held closed loop under boost until you hit that point where it decided to go open loop which immediately caused a lean condition??? Jon, do you have a wideband 02 installed?

D...better wear a diaper.
Scott, Motec WB was in for tuning and we were datalogging as well, didn't react fast enough to show a lean condition. Did show we were spooling quicker than we expected though. Piston never departed, continued towards TDC and bent the valves, left a nice trail of iron and aluminum behind the car though, I should show you a pic of the oil pan repair. Sounded like a shotgun went off man.

It seems like the tuner should accept some responsibility... Especially given that his job is to safely tune the car, which generally means obtaining stable (conservative) boost and stable A/F before gradually turning up the wick. I'd be looking for compensation. A civil court would look kindly upon your case unless you signed some sort of waiver.

I would have to agree with Scott on this one

Guys...don't worry about me, that situation's been more than handled. I was more upset by a CL member who was helping out and abandoned ship when things got tough. Hoping to have the resistor pack wired up and some low boost tuning done by the middle of the week. Gazi...how's your's? We'll have to get the locals together soon for some tuning runs, would really like to rent out Atco for a night if that's doable.

However, the tuner really only has your word to go on, as far as what state the engine is in. And I can imagine the Injector Drivers in the ecu operating the Peak And Hold's at lower duty cycle. So you appear to be running fine, good A/F ratios, but then you go for a pull, and the Injector drivers can't supply the demanded current, at the higher duty cycles.
Tuner's should be getting indemnity forms signed anyways. If SP-performance didn't step up and make things right, I could see a negligence suit being filed.

Sorry LL, I can see we're kinda jacking the thread.
