Is it worth tuning a mostly stock Tahoe for power on 87? YES! Big gains for a stock truck.

I had a smoke test done for a large evap leak and the guy said he couldnt find a leak sp suggested me to have him tune it for $500 ive been stalling ever since he did a timing 2 degree and tune out the large evap code, so i now i gotta buy my own tuner and fix what he did

[@KAS470]

Negligible and you need a higher out put alternator for the fans. A clutch fan will out cool e fans. The one positive off e fans is cooler ac in traffic lol

[@Clearlykevin]

@@KAS470 I have e fans on a stock alt why would you need a bigger one, not undermining what you’re in generally curious

[@KAS470]

@@Clearlykevin was your truck factory equipped with e fans or did you install them? The reason for needing a higher output alternator is because of the amperage draw they produce. A lot of people have gotten away without upgrading but it’s best to have a higher output alternator to keep all of the other electrical circuits happy when the fans are being powered on. If you look at the output of the alternators of Chevy trucks that came factory with the e fans, you can see that they have a higher voltage alternator than the trucks that came with the clutch fan.

@@KAMBAMRBXI have e fans on my rcsb The only thing I noticed is on wide open throttle the headlights dim a little other than that I don’t notice a difference with e fans AC still gets little warm at stop because it takes in all the fumes from the exhaust, the only difference I feel performance wise is it revs quicker but then again rebuilt motor with fbo SB intake and all that of course it’ll rev quicker

I've been wanting to cam both my suburban and yukon xl, but I dont have the funds, and now that I have seen HPTuners, I'd like to get a tuner for my Suburban, but i mainly just want a chop though, since I just park and play music, id just like to sit there and chop the hell out of the ground, and I don't care for performance since thats all I do with it, its not a daily, its just a show rig, and I'd like to know more about the tuners, I've watched a few of your videos

I got a 00 suburban with 5.3 and I did a different muffler off brand but sounds good kinda a straight through but still stock cats. Cold air intake and new clutch fan, water pump, pulleys, spark plugs and wires. Rn getting trans rebuilt with new converter and a fairly low mile used 3.73 rear gear. What would you guys think I could make by fixing some of the things like the afr and timing?

[@nufnuffz28]

Id like to see 20 or so and MUCH better drivability! Big improvement for sure

[@mu9627]

Magna Flow converters helped mine out, buddy even noticed the difference in the exhaust note too. Has better power even if slight, it was noticeable. Can't wait to get a real tune though. Great vehicles, better than new and parts still out there thankfully. Good luck. Oh, the magna flow converter has a different bend on drivers side that makes it difficult to get the stock large diameter front driveshaft out if needed. I went to the later model smaller diameter driveshaft and no problems. Yeah, bit more $ yet new shaft and joints included at over 200K miles.

[@chrisreynolds6520]

No wonder these have always felt weak in the low/midrange to me. Good gains, but still 40 ft/lbs less than a tuned 5.7L. Both my TBI 5.7L and L31 5.7L made over 300 ft/lbs at the tires after tuning.

[@nufnuffz28]

Yeah, LS loves RPM

[@chrisreynolds6520]

@@nufnuffz28 I like torque. LS engines make alot of noise and don't do much when you are moving 13K lbs of vehicle and trailer. My 383 SBC making 500 ft/lbs at 3,0000 rpm drops out of overdrive and accelerates up the same grade in 3rd gear that a 6.0L has to hit 2nd gear to hold speed on. My 8.1Ls in my 99 Tahoe and my 83 G20 run up the same grade in overdrive.

@@PGG909 GM kept the 350 in the GMT800 body style until 2007 in Mexico where the emissions standards were more relaxed. I had a 2003 Sonora (Mexican Tahoe) 4x4 with a L31 350 and a 5spd manual. It was a far better running vehicle than the 2004 2wd Tahoe I had with a 5.3L and 4L60E. No comparison at all with a 4,500 lbs boat behind them both.
