No. Dodge 5.7. Apparently it was a pretty common thing. The rear cylinders like to snap the bolts. I?m thinking it was mostly an issue with the bolts more than anything. Seems to be common in the 2010 to 2012 range but I haven?t read much about it after that.

My Hyundai engine is gdi too and folks go anywhere from 75k to never.

Considering how costly that can be I would make sure it?s really needed. The A4 folks who did it say there really was no noticeable improvement. YMMV

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.

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

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.
