Default Something is not happy in my engine.

This whole thing started when I put on my ETS 3 inch front mount inter cooler. it ran fine for a bit then one night i got on it and after about 7-10 psi it started to get chocked up so i let off the throttle and it has been a problem ever sense. We did some hits and data logged and it looked like it was running lean so we decided to put a new fuel pump on ( AEM 340 E-85 capable). Drove it and it got to 9 psi and started to get chocked up again. this is happening under wide open throttle and partial open throttle.

the purge valve solenoid did brake off when we went to replace the power steering pump and never got around to replacing it, also i am still on the stock turbo.

i am just reaching out to the community to see what you all have to say.

Thank,

mods:
cobb v3 AP
stage 2+ 93 octane tune
cobb up pipe
cobb down pipe back exhaust
cold air intake
forge BOV
flowed injectors
perrin turbo intake tubing

You're running Stg 2 tune with totally different parts. I would not expect that to run right at all. What CAI are you running?

Happy to help you with an e-tune.

No it's a perrin turbo intake tubing with a cold air flow filter on it.

Your map is not meant to work with these parts. You need a pro-tune. If you continue running this map your engine will pay the price..

PSA for the OP:

Anytime you modify something to these cars, that affects Air, Fuel, or Spark, it certainly will require a tune.. For example, lets say your car is a "Stage 2 Setup" (read the notes on your map, it will tell you specifically what it requires or visit cobb tuning and read the notes there). And you add, JUST an FMIC... You have effectively added 4-6 feet of tubing (hotside and coldside pipes) , not counting the much larger intercooler, which alters how long it takes for boost to get to your throttle body, intake manifold, tgv's and intake ports on the heads. You haven't "changed" anything else, but that delay in air alone messes with when it gets to the engine, thus fuel trims get skewed and problems occur. These cars are not tolerant to making changes, even minor ones. I know I see threads like this one, on the daily on Facebook. The frustrating thing is, most people think of these cars as a "typical import" or "Honda like" and think they can throw 2-3k in parts at the car without a tune, then get upset when 2-3k in parts costs them 5-8k in an engine rebuild. Take your time with modifying it. Get used to it and how it reacts to each upgrade, and make sure you get solid tunes for the performance modifications.
