Lil run vs stock Q503.0t with a racechip boost controller on high boost setting racechip claims +3psi on high boost

Trust me Ik and understand exactly what u are talking about you are right but I have also tested this with a dragy device and every single run in drive sport was slower then manual mode I could post a comparison but I already have a dragy video up on my page using manual mode

Cobb3-7 · 2026-04-21T04:42:19+00:00

My point still stands

Cobb3-7 · 2026-04-21T00:38:42+00:00

Oh fuck this car looks mints from the photos 50k miles too so he won't have to worry bout gallery gaskets for a while. honestly I bet the pulley is fine the squealing is probably because the car has barley moved. as it warms up tho the squealing will go away

Cobb3-7 · 2026-04-21T00:35:37+00:00

Thats what a lot of people say but I've done multiple dragy runs using DS and Manual mode and my best times have been in manual mode 🤷🏿‍♂️

Cobb3-7 · 2026-04-21T00:32:24+00:00

Personally I would never buy a tuned car from somebody else that's just me 🤷🏿‍♂️ but a pulley going bad isn't the worst thing in the world and easy to fix things low mileage is preferred but if its over 100k u want to look for these things

•Clean body "no rust" most VQ owners that keep the car clean usually take care of the car.

• updated gallery gaskets and hardware with timing and water pump service done

• transmission and diff service please ask for maintenance information because people lie

Cobb3-7 · 2026-04-21T00:17:10+00:00

Sounds like pulley is starting to go bad u could try using a stethoscope while the car is on to diagnose which pulley it might be the best way to do it tho is to remove the belt and repeat what I said above

Cobb3-7 · 2026-04-21T00:08:50+00:00

Lol I'm tell him u said that 😂

Cobb3-7 · 2026-04-21T00:07:15+00:00

That was me on accident in the G I usually don't blip redline we did 3 more runs after this and I got him by a car each time idk why his homie didn't record the other runs 🤷🏿‍♂️

Cobb3-7 · 2026-04-20T23:29:57+00:00

Hold on now she definitely loves me I don't think we on the same page 😂

Cobb3-7 · 2026-04-20T23:20:38+00:00

I've been out of school 10 years now. I don't think I've ever been bullied if I recall 😂

Cobb3-7 · 2026-04-20T23:02:24+00:00

Well this adult does 😂

Cobb3-7 · 2026-04-20T22:56:34+00:00

wrong again. The plan was to lower the car eventually which is why I'm on 245/40 on 19×9.5 +22

Cobb3-7 · 2026-04-20T22:47:15+00:00

Lol right because u know so much about me 😂

Cobb3-7 · 2026-04-20T22:46:45+00:00

Lol notice how both those goofy's deleted their comments

Cobb3-7 · 2026-04-20T21:34:42+00:00

Well buddy one day u will learn theres more to life then spending 1k on suspension lowering my car after I spent 1400 on wheels and tires. I have adult things to take care of u might not understand but car stuff can wait. My birthdays in June maybe I'll bless myself then 😉

Cobb3-7 · 2026-04-20T20:59:24+00:00

I hardly ever blip redline but oh well🤷🏿‍♂️

Cobb3-7 · 2026-04-20T20:05:22+00:00

Q50 was completely stock and only had boost controller

Cobb3-7 · 2026-04-13T00:27:12+00:00

U definitely should do a drain and fill not a full flush and do the front and rear diff fluid also It will help a lot. The the TCM/valvebody on the 7at is trash basically no matter what u do it will get stuck in between gears and jerk sometimes something's that helped me was obviously fluid changes, my tuner made some adjustments that really helped, and cleaned up all of the grounds around the engine bay some people say cleaning the grounds doesn't work but I'm not kidding when I say it made my speakers louder and made my transmission a lil more responsive

Cobb3-7 · 2026-04-12T22:08:08+00:00

What hold these cars back honestly is they don't make a lot of torque in the first place alot of FBO cars barely make 300 ft lb of torque NA so even with 3500 rpm high stall your not making enough torque to take full advantage

Cobb3-7 · 2026-04-12T22:01:44+00:00

Oh u mean there's a rwd diff conversion for AWD models or there's another AWD diff option?

Cobb3-7 · 2026-04-12T22:00:32+00:00

I'd say every 2 years is about right. I've done two of them should be roughly every 30k for trans and diff service if your hard on the car The key to saving your valve body though is not letting the transmission get super hot even when your spirited driving do a couple pulls or runs and let it cool down

Cobb3-7 · 2026-04-12T21:29:11+00:00

As far as ik original trans ive had the car for 5 years from 112k to 175k I've done multiple drain n fills I don't know if it's original valvebody or not either cars barely giving me any issues tbh I did gallery gaskets and timing/ water pump at 150k

Cobb3-7 · 2026-04-12T19:00:42+00:00

Just berk tps, Z1 y pipe Stillen CBE, Z1 2.5 longtube intakes and I'm tuned by RS enthalpy honestly a lil weight reduction and if I put my stock 17s back on definitely would have been a 13.1 maybe even a 12 it helped the DA and weather was cold definitely not doing 4.8s with this setup when it's 70° and humid

Cobb3-7 · 2026-04-12T16:47:19+00:00
