    Fixing Ceramic Coating faux pa

    Okay smart people! I have a question regarding fixing a ceramic coating mistake. I ceramic coated my car, two years ago, this October (which is why I suggest having it done professionally). :) While I'm VERY pleased with how it turned out, I apparently had an interruption while coating my...

    Bilstein struts and shocks

    So! I've seen some threads talking about (and mod lists), of people running the Bilstein B6 struts and shocks. Are they different from stock? If so, how? I've got H & R's, and like typical lowering springs, they make the car a little bouncy on poorly constructed roads. It'd be nicer to have...

    Oil Weight

    Okay, I'm pretty sure I've seen this question asked, but I can't find it. My question is....the owners manual says 5w-20 motor oil, the oil cap says 5w-30 motor oil. WHICH IS IT!? I'm GUESSING the lighter one, but what does everyone here use? Please note that I'm not trying to start a war...

    What are my options...

    All right machine shop peeps! Never having tapped a hole before [careful with that], I managed to basically ream out the hole I drilled for the PTU drain plug. :| SO! What are my options at this point? ...besides getting a new PTU (this one I figured out on my own). Anything self threading?

    How long until OAR registers new fuel mix

    So I mixed a weak tank of fuel which gave me an OAR of -.59. I corrected it and drove about 5 miles....but it still read -.59. How long does it take for the system to recognize the new mix? As always, thanks in advance. S Sent from my Pixel 4 XL using Tapatalk

    Manifold air density

    Hey everyone. :) Now that the Banks iDash has been out for a little while, I'm wondering if anyone has any manifold air density numbers, for any level of modifications for the SHO. I'm really wanting to get one and I think it'd be nice to see how my current MAD compares to a stock MAD. Or at...

    E30 Calculator for Android?

    Hey everyone. I'm making the switch from iPhone to Android, and I've really fallen in love with an iPhone app called CalculatE85 (https://apps.apple.com/us/app/calculate85/id1246394696). Unfortunately, that developer doesn't make an Android version. SO!....besides web sites, what apps are...

    WPCtreatment

    So...based on the revelation of what bpd1511 is doing to his PTU....I have a thought (which I'm REALLY thinking about pulling the trigger on). Buy a new PTU (which I've seen new for about 650-ish), disassemble it for the wpc treatment. Then swap it in and sell the old one on eBay. Or wpc...

    Wrap the cats; yes or no?

    So my PPE cat'd downpipes came Monday and I want to wrap them before installation. ...and they are a thing of beauty. This seems to be along the lines of a religious question but... Should I wrap the cats or not? I think the cats will be biggest heat source... So not wrapping them makes me...

    E85 70% ethanol octane rating

    Okay...so I'm looking around at the E85 stations and i see some places with 70% E85. Now...I thought the 85 in E85 meant 85% ethanol. ...looks like it doesn't. Does anyone know the octane rating of E85 with 70% ethanol? Sent from my iPhone using Tapatalk

    In case there's any question...

    This car is an AWESOME highway car! Especially with a tune! I'm currently running H & R springs, DiConzolo lower mounts, GH IC, GH tune & SP 542's. Cat'd downpipes on the way. MAN it drives fantastic on the highway. AND...the stance with these springs....makes me a) smile as I approach and...

    Upper strut mount orientation

    My apologies for the cross post, but I'm not sure the subject I posted it under has enough traffic (I'm used to a faster response time to questions from you all). And...this question fits here as well, since it's stems from putting H&R's on. Can anyone tell me the correct upper strut mount...

    Tune after GH intercooler?

    Hey there. I've seen some people say that a tune needs to be updated to properly handle the new found air flow with the new GH intercooler. I've ALSO seen some people say that you can go back to stock without fear of having the GH intercooler still in place. Those two seem to be mutually...

    Upper Strut mount orientation

    Hey everyone. I know on the upper strut mount, one of the sides has a Delta symbol. Does that Delta symbol go towards the center of the vehicle or the towards the outside of the vehicle? Thanks in advance, S

    New mods ordered!

    I'm pretty excited! I ordered the intercooler and cat'd down pipes yesterday! With a 3 bar and a Gearhead tune, what kind of hp and tq numbers should I expect? ...Im trying to curtail my excitement somewhat. I've heard that the intercooler is worth about 40 and the down pipes are worth about...

    Why 3 bar MAP?

    if 1 Bar is 14.5 PSI, why are people changing our the 2 Bar MAPs for 3 Bar MAPs? Wouldn't a 2 Bar MAP be good to 29-ish PSI?

    Rear O2 tune question

    Okay...I've been reading all the posts regarding tune's with and without, the rear O2 sensor enabled. My question is; why disable it in the first place? Does it hurt something to leave it enabled?
