1. Can you give us the rundown on where the ECM begins life, who it gets shipped to and from? (Flight systems, to dealer, to customer) Someone may be able to word this better....

2. Can we PLEASE get the friggin compressor effeceincy map?

3. What is the commanded AFR under WOT on stage 1? Stock?

4. What are the largest injectors you have tested in this car period?

1. Explain more about the Engine management system (like parameters, boostcontrol, knockdetection, timing control, ionizationmetering)?
2. Has the CSRT4 been tested on Nürburgring-Nordschleife or another official track by the SRT team, and if that was the case, what was the best time?
3. Explain more technical specs about the stock IC (like max flow, efficiency, air fillrate).
4. What's the camshaft spec for the CSRT4? (lift, EVO, EVC, IVO,IVC)
5. What sizes are the valves?
6. What's the max torque allowed on each gear (through torque limiter) and also max torque through the gearbox (mechanical max torque)?
7. What's the spec of the stock injectors?
8. What's the stock fuel pressure?
9. What's the stock fuelpump maxflow?
10. What's the spec of the pistons (casting, rings, bearings, pin)?
11. What's the approved max torque of the drive axis?
12. Explain more the function of the flow-valves in the intake manifold?
13. What's the difference between the 2008-2009 model (technically wise)?
I asked these questions for you guys

As for the fuel injectors, the Caliber SRT4 uses the same core fuel injector as the Neon SRT4 Stage 1 (2003) and production 04-05 Neon SRT4. We have implemented some durability improvements on the Caliber SRT4 version, hence the different part number. These injectors are more than suitable for both production and stage 1 CSRT4's. Due to inefficiencies in the Iron Block Turbo from the Neon, that engine required more fuel than the Aluminum Engine in the caliber.

Don't waste your money buying Neon Stage 1 injectors for your Caliber!!!!

2. Has the CSRT4 been tested on Nürburgring-Nordschleife or another official track by the SRT team, and if that was the case, what was the best time? The caliber has not run "The Ring", but has performed on various other tracks around the US and performed very well at each.

4. What's the camshaft spec for the CSRT4? (lift, EVO, EVC, IVO,IVC) Intake lift = 9.2mm / Intake Duration = 219deg, Exhaust lift = 8.4mm / Exhaust Duration = 216.5deg

6. What's the max torque allowed on each gear (through torque limiter) and also max torque through the gearbox (mechanical max torque)? Stock Car - 214ftlb in 1st, 245ftlb in 2nd, 265ftlb in 3-6. Stage 1 - 240ftlb in 1st, 300ftlb in 2-6.

7. What's the spec of the stock injectors? 577cc/min - SAME AS NEON SRT4 STAGE 1.

8. What's the stock fuel pressure? 75psi

10. What's the spec of the pistons (casting, rings, bearings, pin)? Everything is 100% unique to the turbo engine with hour and hour of development time on them. Rods are bushingless forged. Pistons are cast and dished with intake valve notches, also an anodized top land and floating pin....very suitable for the turbo engine. Tri-Metal (w/lead) Main and Con-Rod bearings...very good. Ring pack is awesome... .

11. What's the approved max torque of the drive axis? You guys tell us

12. Explain more the function of the flow-valves in the intake manifold? The "port flap" is to generate tumble at low speeds and idle which vastly improves emissions and idle quality....it basically partially blocks the intake port to the head. Then when we need peak flow for performance, the "port flap" moves down to unblock the entrance to the port.....pretty neat eh!

13. What's the difference between the 2008-2009 model (technically wise)? Check caliberforums for this...its in a few posts...major items are MyGig radio and 3-Mode ESP...amongst many other things.
