I have the level 1 OBDII add-on from these people on my '98 Tahoe, it has definitely helped. So this: https://www.performancechiptuning.com/voltage-performance-chip-battery-module-raizin/ makes me wonder. I imagine it's basically holding the electrical system up to nominal from the get-go...

My '98 Tahoe has to sit a bit more than it's been used to, with fuel prices hiked a lot, so I put some of the most common fuel stabilizer I've seen here -- Sta-Bil: https://www.goldeagle.com/product/sta-bil-fuel-stabilizer/ in the tank with fresh gas. And I was surprised. It helped a lot...

Just realized that one of my happier yet very out-of-band habits hadn't made it here yet. For several years I have been adding one ounce of 2.5-micron HBN to oil changes in my '98 Chevrolet Tahoe. Usually I mix it with one of the quarts of oil. Definite improvement. Feathering the gas...

I've finally got Stage I of my rig to throw ionized air into the intake, in apparently stable condition, the gotchas seem to be under good control. So now I need to build Stage II :-) After trying a number of things, the simplest seems to be a switch to "detect" throttle position. Anyone have...

Well, I've starting thinking again (that can be dangerous) about my charged-air project. It's very nice and stable now. So it's time to think about a next level. Probably a "secondary", turned on (optimally) when airflow rises in the filter compartment. I tried a couple very popular tach...

I ran K&N for a while, and then my Mass Air Flow Sensor died and I had to replace it -- and there was this thin layer of red dust on its inside. Didn't like that at all. I've found a few makes of oil-less washable air filter, but none which seem to fit my stock air intake. Anyone got a...

Just had my plugs changed, 1998 Chevrolet Tahoe, 5.7L V8. Am really curious what the wise ones among us might have to say. Most of the removed look like this (all of them AC-Delco 19256067 41-993, reportedly Chevy default recommend iridium for this vehicle): But one of them, is the below...

I have some electrical widgetry I'd like to switch on progressively, starting with off-idle status. Stage 1 is turned on at ignition, stage 2 is to be added at off-idle, then stage 2 gets turned off when back to idle. What's the simplest way to do this for the general automotive case?

A month or three ago I replaced the mass air-flow sensor on my '98 Tahoe. Improvement was clear. What shocked me, was the thin layer of red dust on one side of the mesh and on the fine wires in the middle. My air filter to that moment, was a certain common brand known for red color and...

I was wrestling some major carbon buildup until recently, on my 1998 Tahoe, upon which a past owner bestowed free-flowing exhaust duals. I ended up replacing all plugs and wires, which helped for a while, but then carbon got plug #4. I replaced the K&N air filter with a standard one, and that...

I'm about to replace the plugs, wires, cap, and rotor on my 1998 Chevrolet Tahoe. When I do searches in auto-parts store web sites with local stores, there is an incredible variety of plugs: platinum (stock, reportedly), double-platinum, iridium, "power nickel" (whatever that means). And when...

I have been doing it for a couple of years now: https://enginefun.ponderworthy.com and I can provide (free of charge) a small number of the air charger units I'm using. If you're interested, please contact me privately, either via this site or email.

Well, I bought one of these: https://www.ebay.com/ipp/224110160424?transactionId=2447316167012&_trksid=p2047675.l48352 and it did not fit my wife's 2007 Ford Focus in a number of different ways. Anyone have an idea as to how to get one that will? I don't want something shiny that will suck...

One of the stranger things I've seen in the aftermarket, is the extraordinary number of "cold air engine intake" replacements which are visibly positioned to suck in the hot air available at the top of the engine compartment, right next to the intake manifold. This is supposed to be better than...

Wow, a great article. I'm pretty sure my Bertha ('98 Tahoe) will accept ECU remapping, because there are a number of aftermarket devices whose literature seems to be saying so, though I had not seen that word "remap" until I read it on these forums. I did notice that the article said that with...

A few months ago I read one article stating that a catch can is a very good idea if one wants to keep a vehicle as long as possible...and then three more saying they're for racing, don't bother, et cetera. Anyone got solid thoughts on this? I have a '98 Tahoe, running well, no hurry to mod it...

We bought my '98 Chevrolet Tahoe used, and within a year it blew a turn-signal bulb in the rear. A really helpful auto-parts store guy informed me that this was the only common issue on this vehicle that he knew of (quite true so far; Bertha, the truck, has otherwise been very nicely reliable)...

About two years into the project thus far. (Cannot upload pix or link here yet, am very new, but many thanks @obi_waynne , for the invite to post this.) Negative ion generators are lately quite common in air conditioners, air cleaners, and other devices; these charge millions of air molecules...

I have an engine mod, rather experimental, where I have to combine fourteen red positive wires into one, and fourteen black negative wires into another. Right now I'm using a kind of tree of crimp-on terminals, which is working well, but which is not very neat. I have found gang terminals for...

Hello everyone! Glad to have found TorqueCars. Not a whole lot of mod work being done here in Topeka, Kansas, but there is some. I drive a 1998 Chevy Tahoe, have been setting up negative ionization to the engine intake for about two years, lots of fun!
