General vehicle thread

I need to get around to the walnut blast on my F150. Have a slight stumble at cold idle. Should help economy too.
Mine has 180k on it though

Hyundai has scheduled maintenance to chemically clean the intake system which should also include the valves. Using Top Tier gas also helps keep it clean.

Top tier fuel doesn't really help on many gdi engines, as the fuel doesn't hit the top of the valve

The hot rod kids run the PCV to catch cans instead of to the engine. So no oil residue gets on the back of the valves. But then you have the smell and you need to empty the can.
Some of the newest engines have a spare injector on the manifold that is run periodically to help clean the valves. Not sure which ones though.

Yeah, I missed out on the year they added the port injector on my model. I do need a catch can too, but the decent ones are out of my cheap ass "willing to pay" range

I should add a water or methanol kit to get the most out of both worlds, but again, I like keeping my money

Apologies if I've asked this before - this is a big thread to dig through.

I have a 2014 Chevy Silverado w/5.3 engine. Are there any shops around the south metro area that would be recommended to do some performance upgrades to that engine?

Nothing drastic, just a little tuning to make it run better - especially throttle response. I want it to do something when I push the pedal a little, instead of acting like a teenager that's been asked to take out the trash.

I would buy a Pedal Commander for $249 and you'll be surprised how much "feel" you get back in the pedal.

I had one on my Gen 2 Raptor and my 6.2 Silverado, and it made a significant difference in seat of the pants throttle response and removed all the OEM delay.

Wow - that sounds like EXACTLY what I need! To fix exactly what bugs me! Where can one find such a wondrous device? Local, or on-line only?

Amazon, have it in a day. You can also buy it directly from Pedal Commander, but I’ve never seen them for sale locally.

You need the PC65.

I know how GDI engines work, so no kidding. It produces fewer deposits in the first place.

It's not the fuel causing the deposits though. It's oil blowby and pcv vapors. Good oil helps, but fuel isn't going to make much difference at all unless you're washing down rings running rich.
Catch can is the only real way to remedy the situation.
