It seems you may have answered your own question with "I’m stock tuned, just bolt on upgrades atm". You are likely having false reports to the ECU now, where a tune would be designed to enhance performance now. May be time to tune it. I have seen where a tuner, even APR, says, in order; 1st) tune it...then intake and then exhaust.
Yeah, the stock computer will always correct the fuel delivery based on incoming air. Recalibrated fuel timing & raise in boost to that management will make use of those supporting parts. I personally discovered 3in exhaust was overkill anyway.

Even with a cai installed the stock ecu won’t recognize the increase air?k
Ecu def recognizes, but the factory program corrects the fuel to maintain 14.7/1 ratio. Therefore it won’t gain anything really unless the ecu is recalibrated with higher performance program. Kinda what I was explaining before. Just throwing parts (which are generally supported mods) alone on computer control injection doesn’t automatically translate to gains in power just because of gains in noise. This has been proven on dynos for years, even on my old Evo 8, mk5 gli or this mk5 R32 currently, computer module re-tuning has made the significant impact, the bolt ons will promote more flow thru the head to go further.
Never heard of that one. I used giac with switchable files, 91 & 100octane programs. But was still slow at the strip at mid to high 14’s cause of fwd traction losses off the line in first few gears. Awd R32 with giac ecu & United Motorsport haldex module flashes I ran best e.t. Of 14.2 1/4 mi. Also handles better at a circuit. Yer honestly better off going with well known reputable flash files, many documentaries on here of what worked best. Personally I think going over 300 on fwd is silly if you can’t disable the traction control & put it to the pavement.
Yeah, Stage 2 for GIAC and APR etc., w/o hpfp.What stage tune wld u recommend? Im not planning to go k04. I know I might be ready to go stage 2 with my current mods, except hpfp upgrade?
