    And those are horses at PEAK RpM, very likely well over 5600RpM. It's why my next 6.0L will use a trucky intake manifold, and whichever pope hat intake port heads get as close to 10.9:1 scr without going over. (Does any tuner have da bawlz to tune a 6.0L OVER 10.9:1 scr?) Power UNDER 4000RpM is...

    How do I get my Tahoe to ride/handle like my 3500HD?

    The rear suspensions simply do NOT compare directly ... but what about the front suspensions? Dimensionally, Tahoe Z71 (1500) may be incompatible with 3500HD steering / suspension parts, but the rates of the 3500's springs / shocks / swaybars would be HIGHLY informative. In other words, the...

    HEADERS, MANIFOLDS & CATS

    When he says 'stock replacement stuff is fine', I do wonder though ... maybe you should pretend your 2011 Chevy Tahoe (1500), is instead a 2011 Chevy Suburban 2500? Basically, are the manifolds and/or Y-pipes and/or cats different between 1500 vs 2500? "stock replacement stuff is fine" if this...

    07 Escalade 6L80 into 12 Escalade - swapping 2012 valve body/TCM into the 2007 6L80

    Something to do with L92 & L9H being compatible with each other. Whereas the L94 having Engine Half @$$ enabled, would have different operating systems. 1GYS4DEF7BR400471 is a random VIN for a '12 'sclade. Plug that VIN into https://tis2web.service.opel.com/tis2web then press 'Get Cal ID' on...

    07 Escalade 6L80 into 12 Escalade - swapping 2012 valve body/TCM into the 2007 6L80

    Just tried to use a random 2012 Escalade VIN at the website I just showed. The website seems to be down for the time being. Point is, you use your VIN to find out about the program segments of your Escalade, then use the other VIN to see if the TEHCM would need to be reprogrammed or not. Again...

    Engine Used Oil Analysis Report & Filter Guts

    I'll use any brand oil filter - but NEVER any brand's 'basic' or 'economy' or 'low-budget' offering. Fram has SEVEN different types oil filter for Gen3 V8s (trying to confuse me, eh?) Purolator has three Wix has two So long as I avoid the bottom-rung ...

    07 Escalade 6L80 into 12 Escalade - swapping 2012 valve body/TCM into the 2007 6L80

    Specifically, I'm concerned about a possible mismatch between the engine and transmission segments. @jrobie79, you obviously have YOUR VIN. Would you have the VIN of the '07 sklaid? That way, I can show you (and everyone else) how to use this website: https://tis2web.service.opel.com/tis2web

    07 Escalade 6L80 into 12 Escalade - swapping 2012 valve body/TCM into the 2007 6L80

    Please keep in mind that I'm a pessimist ... Unfortunately, the odds that the software that operates BOTH '12 AND '07 sklaids is IDENTICAL, is very low. GM had already started down the path of making things unnecessarily complex in the EARLY 2000s. You can either have the TEHCM re-programmed...

    Running A CVC BU60FHD Converter with Zeroed-Out Clutch Slip Target -- Any Advice/Experience?

    Shouldn't be too hard, very common gear for GMT800 & GMT400. Think 'Less and/or Later TCC LockUp in 4th than GM OE' ...

    Shorty headers worth it for 5.3?

    Problem with that claim - may or may not be true, who knows? - is total lack of specificity. 12hp @ what RpM? If it gains 12 hp @ 3000RpM, BUY IT GOTTDAMNT! 12hp @ 5000RpM, you may not notice. 12hp on a 4.8L? on a 5.3L? on a 6.0L? on a 6.2L? I prefer stopwatch or time trap measurements over '+...

    Running A CVC BU60FHD Converter with Zeroed-Out Clutch Slip Target -- Any Advice/Experience?

    3.42 will make life easier on the engine and transmission, better city MpG too. Disabling Engine Half @$$ is not as good as deleting it, but every lil bit helps. A well-rewritten shift schedule (post #3 by Foggy) sacrifices 1 or 2 PEAK MpG, but the 6L80E will last even longer. Vast majority of...

    Engine and gearbox swap from four speed to six or eight speed on 2008 Z71 ?

    Miles per Gallon? 6L80E. Miles per Transmission? That depends on who last rebuilt them. With a proper rebuild using updated materials, a decent pcm / tcm tune, & fresh ATF every 2 years, I see no reason why either would not last 150k miles. On the other hand, any OE geartrain lasting 150k miles...

    99 2dr Basic Tahoe, diesel possible?

    https://en.wikipedia.org/wiki/Chevrolet_K5_Blazer#Third-generation_(GMT400;_1992%E2%80%931994) https://en.wikipedia.org/wiki/Chevrolet_Tahoe#First_generation_(1992) https://en.wikipedia.org/wiki/Detroit_Diesel_V8_engine#6.5L Think a DuraMax 6.6L is also possible, just not with GM OE parts ...

    Running A CVC BU60FHD Converter with Zeroed-Out Clutch Slip Target -- Any Advice/Experience?

    If you want to give your engine & transmission a wee lil extra protection against overheating, 1) Leave the 'DOD Enable' selector Enabled (yes, I know what I said, please read on) 2) RAISE the 'DOD Enable Engine Coolant Temp' (Min Engine Coolant Temp before V4 mode can enable) to 230F / 110C...
