GM Performance

see I don't get that world record stuff with production trucks - I think the only reason it got that is because they didn't put a speed limiter in it. Period. You really think im on par with a an SRT10? hell no. a stock 4.8L w/ 4.10 gears and 32" tires and bolt ons with LS1edited features. i didnt m...

I'd put money on it, that it would hit 130/140.

My silverado has hit 152mph pin nailed down on 100mph, before i backed off (didn't feel like blowing a tire at that speed.)
granted - it took it a little while to get up there. vette did it in a blink.



(using efilive & gps)

don't think i ever heard?

I'd just replace them. your due anyways. Synthetic goes and eats away at any build up of old oil.and thats what happened. I always ran synthetic in my '01. and around 35k when i switched out my gears & carrier. re replaced the seals then (said they were weeping) same thing with yours, you just got a...

I'd assume since it's 8 lug - they aren't as popular. Your vast majority of people who want the bigger wheels are buying base - LS models 1500 (tahoes and silvy's) which are 6 lug. There isn't THAT big a market for 8 lug 20's by comparison to 6 lug. Chevy just thinks its a work truck anyways..why fa...

a note on the gapping.

supercharged/ high compression = smaller gap

lower compression, N/A = bigger gap.

depends on coil and engine type too.
I experimented with this some on a v6 best was just stock gap... woopee. but idled better +/- ?

ignition boxes work like this... like they say about headers, intakes, exhaust "improves gas mileage!" depends how you drive it. Personally I've had 3 msd boxes. - depending on the vehicle, it will change the exhaust tone. It will lean the mix because you are actually getting a complete burn as it h...

Hope I'm not to late with jumping in on this one. but I only run ProComp MX-6's. I have them on my tank of a tahoe on stage 6 which is like civic tight. Handles great, never gives me any problems. ultra control under trailering conditions. On my Silverado I had edelbrocks up front and mx-6's in the ...

Since its new.. and just a gear swap. You can look at about 250-350 per axle. + parts. on average. always depends on the shop. if its low-low price be careful. It is NOT easy to install gears, and 4.10s will whine normally (only gears that don't are factory GM and even then they still -can-) my rear...

Just curious what software you used to get those figures? On my 99' Tahoe I ran EFI Live v5 and i get + 15-19% LT fuel trims, about equal. (which assumes im running lean.) vs yours running rich and removing fuel. to me both are pretty extreme. I hope its just because EFI live was built more for Ls1 ...

ditto..asstek is trash. It's there for the guy that wants to make the leap from a cavalier to an suv.. might I add, they usually like them purple or that desert brown color...yick. avalanches r puke to me. granted w/o the cladding, and properly dressed they arent so bad. I got to drive one slammed o...

autozone did that to me too. and often times the seal is not set right on the tube. Make sure you remove the OLD seal in the transmission too..... often times guys dont do this. or dont realize its a seal because its metal on the outside rubber inside. it can be a pain to remove if jammed in there a...

you need remove that bracket. Its got torx key bolts. A typical universal torx tool (multiple sizes) works great. Ive removed it 3x without any problems. you wont need to remove the y pipe just that bracket.

didn't we read back some place KB released a fix for whipples. Same thing, injectors and went dry with a different tune and netted like 50more hp? he's not wrong. whipple is.. whipples supercharger is fine its the fueling that goofed everything up but.. consider when it was released it was a good th...

ouch.. man at 15k miles on my 01 silvy ...... i was like crap i should have changed this 5-10k ago.. clear up to 60k i was thinking these thoughts. thats a rough one man......... that filter is got to be stuffed with dust. and that filter doesnt filter well to begin with im sure its recycling dust. ...

hey just curious, what was the cost on all this? and also how are you guys tying the injectors to the stock computer. or are you doing like a megasquirt setup?

My cousin likes his gibson exhaust, their stuff is pretty good had a set of shorty headers.
Flowmaster should have a set.. Summit has an offbrand exhaust kit i think.

and I had a jardine which was nice 3" mandrel bends, + strait through muff...

what the hell. . .

gee I like all the chrome and the naked lady emblem on the grill. classy.

so right before your civic gets run over you can be watching fast in furious in your rear view mirror. Nice.
