I’m trying to decide if I want to try a flex tune. We don’t have enough e85 around my area that I’d be able to run exclusively ethanol, I’d like to be able to fill up with 93 when I need fuel and there’s no E around so a dedicated e85 tune that adds more timing down low is not an option. I’m...

I’ve never had proper longtube headers on a car before so I’m not sure if this is normal or not: Just bolted up a set of Texas speed longtubes with off-road midpipes. Fitment and quality was beautiful. Zero clearance issues anywhere. I’ve put about 300 miles on the car and it runs strong...

I have had a Lund 93 tune for my stock 16 GT for a few years now. I just finished putting a set of off-road longtube headers on the car and am wondering if it really is true that the car will “learn” to adapt to the headers, and how I can tell. I am now monitoring LTFT and STFT on the nGauge and...

2016 GT, almost completely stock. Lund 93 tune is the only real performance mod. The car used to be a weekend toy for me so when I drove it, I usually drove it pretty hard. A few months ago it became my daily and I've felt lately that it just doesn’t seem to be running as strong as it used to...

2016 GT with Lund 93 tune, otherwise stock. I filled up today and happened to notice my ngauge show a brief blip of positive knock at part throttle as I was getting on the freeway. Not completely unheard of with my car but usually not under these circumstances. I watched the gauge for the next...

I've searched the forums for info but so much of it seems conflicting. I am looking to get my car aligned. I have 1" drop springs and no other suspension mods. I will be ordering a set of camber bolts so I can get some adjustment in the front. I have a phenomenal shop that will work with...

I'm looking for a set of factory foundry 20s. I found a set that the guy claims were taken off a brand new car with less than 100 miles. They have Goodyear eagle f1 tires and he swears up and down these tires came on the car. I thought all the factory 20" cars got p zero all seasons. I'm not...

I'm going to a 19x10 square wheel on my GTPP. the p zeros on the rear of my car are trash but the front are still really nice shape. I intend to run 285/35 square on all 4 corners but I'm considering just reusing the 255/40 on the front until the wear out since I'm cheap. Will a 255/40 fit on a...

I'm ordering a set of 19x10 +35 GTPP replicas from OE Wheel distributors. They come with center caps that have their logo on them. Their listing (and others on this site) have confirmed that the factory centercaps with the pony logo from GTPP wheels fit. I want to get a set of OEM caps to make...

I'm looking at buying some used Vossen CVT. The guy selling them had them on his s550 but doesn't know if they are hub centric or not. He says he doesn't remember using hub rings, but it's been a while and he's not sure. Can anyone confirm if these are hub centric wheels? Thanks

I'm wanting to run a 19x10 square setup with 285/35/19, but first off, I'm not sure if this is feasible. I know it would probably fit, but will it look goofy? If all 4 wheels are the same offset, with the front (or rear) stick out more? I happened to come across a wheel that I like in...

I have a 2016 GTPP with right at 9k miles. Up until now it has been just a weekend car, but its now going to become my daily driver. When the car had about 2,500 miles, I put on a set of very mild 1" drop springs (Steeda Sport Linear). I had an alignment done about 500 miles later. I...

When using a slip-on wheel spacer of negligible width (5mm, 7/32", 1/4", etc) does anyone make a spacer with an additional hub-centric lip or are they going to be flat? I don't remember how deep the hub is and want to make sure the wheel still slides on enough to grab the hub, or at least has a...

Looking for a set of new/low mileage takeoff factory 20s with tires. I'm in Nashville, TN and would rather not mess with shipping but would travel a few hundred miles if needed. Thanks

I have a set of 25mm coyote brand spacers at all 4 corners with my OEM PP wheels. I used the supplied small acorn nuts to secure the spacer to the hub, and the OEM lugs to hold the wheel to the spacer, all torqued to 130 ft/lbs. I have not had any problems with this, but I'm wanting to swap...

What's everyone's thoughts on the availability of the upcoming GTPP2 wheel/tire new takeoffs. Do you think they'll be sold pretty regularly? Or will people opting for the PP2 be keen on keeping them? Do any of you guys that plan on buying a PP2 intend to run aftermarket wheels? I want a...

I have posted this question before but now I have a video to go along with it Sometimes for no apparent reason my car will open and close the throttle body very rhythmically every 2 seconds for 3-5 cycles when at idle. It doesn't not matter if the car is hot, cold, or anything in between...

I've flashed several different tune revisions from Lund, and have gone back to stock a few times too. At least 3-4 out of the 5 times I've flashed back to stock I've had to perform a crank relearn. I don't think I've ever had to do this after flashing one of lunds tunes. Does this indicate...

I see some intermittent knock at throttle tip-in and am trying to determine if it's real or false. I've mixed in some vp octanium and saw no change but would like to try some actual race gas as well. I know that certain oxygenated fuels have a different stoich than the standard e10 the car is...
