I stall the stage 2 kit with a high flow cat and a tune with it .yeah definitely fell the power My gxp dyno at 320 at the wheel and over 400 of torque

I just want to add that you are correct about the forged components in the earlier 2.4 cars, however it began 2006, and I believe I had read just recently it was 2006 and 2007 that had the forged components and then it stopped in 2008 and on. I have a 2006 2.4 with a turbo setup that looks exactly like the one in this video except different brand.

@@TheNobleLoyalist just to correct since I've researched this endlessly enough to become a mild expert on it, the 06-07 le5 was not forged BUT the rods were made from gkn sintered metal (gm referred to them as forged due to higher strength, but dont be fooled they handle far less than a real forged rod) and the 08+ rods were made from c70 powdered metal, this difference in manufacturing technique made the later rods weaker. The le5 crank has never been forged but does seem to handle north of 500whp without problems. The only forged ecotec crankshafts came in the lk9, lsj and lnf blocks. A base le5 from early production runs can handle a little above 300whp with a properly tuned turbo, the later series blocks handle about 250 reliably but as with all mass production these are ballparks not absolutes. With rods from molner or carillo and pistons from wiesco or diamond you can see 5-600 whp reliably using methanol injection to keep the cylinder liners cooler( ecotecs love methanol injection). The biggest problem with running high boost is the entire valve train is a hydraulic system that uses oil fed lifters to keep the cam in contact with the rollers and actuate the valves. The higher the boost the more trouble the lifters have overcoming the cylinder pressure on the exhaust side eventually leading to valve and piston touching and destruction. Gm itself switched to solid lifters on its drag ecotecs.

Job Done Right - The charge pipes do allow for better airflow at higher engine rpms, and with higher lb/min airflow from the turbo charger. These are a supporting modification that allow our Stage 2 and Stage 3 tunes to breathe easier in the upper RPM range. Simply adding the pipes themselves without the tune will not gain you any power, since the ECU's stock program has a "learn down" feature that prevents the engine from making more than the factory programmed power output. All of our tunes have the "learn down" feature defeated. DDMWorks does not tune the Solstice and Sky first hand, and do not have the tuning experience with these cars that we do. They use a 3rd party service called Trifecta to provide a tuning solution for their customers. We write our tunes in-house for each unique customer's car, and perform a few hours of datalogging and revising of the tune to calibrate the car properly. The charge pipes happen to be nicely cosmetic as well, which is an added bonus. We paint ours either to match any factory color, or in custom colors depending on your preference to really help them stand out under the hood.

So, you had stated that we need the stage 2 and 3 tunes done by you guys. Is that something you do on the computer or do we have to bring our car there? I'm hoping you can do it over the internet since I live in Ohio and coming to AZ. isn't an option.
