Some of the 8.1 guys over at the high performance forum are disapponinted with the Westers. Are the results better on the 4.8/5.3 side? :chevy:

I'd like to see dyno results before and after. The program for my truck is $595. The same money will buy a high stall torque converter less installation, but worth an honest .4 in the 1/4 mile. Of course the Westers will do other recalibrations. :chevy: What to do?

basically we talked about everything.i mentioned that i had a free flowing exhaust with the headers,cats,bullet mufflers,true dual, and x-pipe.he said he could tune for it to take full advantage of the flow.he is going to raise my idle to 625 instead of 550.i measured the tire by marking it and the concrete to get the speedo correct.shift points are going to be 5600 1-2 and 5500 2-3.he is going to set the kickdown different so that it will down shift instead of staying in gear like our trucks sometimes seem to do.he also stated that he does leave a tiny bit of tq in so that the shifts are very firm and you will not experience the slight hesitation when shifting at wot.i told him i had a 180 therm.i mentioned that i had the iridium plugs. he said that they will work fine but i think i am going to go to a step colder.we talked about the mass air sensor. he said he could tune for no screen but he does prefer to leave it in since it is able to get a better reading to the pcm.lyndon is a great guy to talk to and is very intelligent about everything.my honest belief is not everyone will be 100% satisfied with his pcm's.every truck and person reacts differently.i believe that i will be very staisfied. :chevy:

So true! Having spent 3 years over at LS1.com when I had my 2000 Z28, I know that the same mod on two like vehicles can have different results. Sounds crazy but true.

That "kickdown" is awesome!!! It is quick and sharp and immediatly puts your motor right in the middle of the sweet-spot. If you are rolling along at 55 MPH and give your truck 1/2 throttle you are up to 75 MPH very quickly!!!

No worries. I'll send you a couple, along with some neat ones for your

mirror. "Objects in Mirror soon disappear..."

I did an experimental tune with your PCM, so let me know how it works.

Everything was as you requested, but I did some different modifications

to

The torque management, and I'd like some feedback. Yours will be going

out

Tomorrow afternoon.

 

Lyndon.

 

now i am really excited. :chevy:

      Sure, but they do have some affordable options like the Trax, Trailblazer, Envista, and Encore. Some of these have a cheaper base price than the Civic, though the fuel economy isn’t as high. The main problem is that people WANT the highest trim with all the goodies and finance for like 7 years. That’s how ppl “afford” the more expensive vehicles.

      Holy s**t - not much of a parts thrower you say? You BLASTED that thing with the parts cannon!  You'd have been probably $1,000 ahead if you had just brought it to a competent shop rather than shotgunning a bunch of parts it clearly didn't need.   Just FYI - oil additives are really, REALLY good at ONE thing ... and that's emptying your wallet. They're ALL useless gimmicks.   If that has the L94 or L99, then #7 is an AFM cylinder. I'd suspect a failed lifter in that case.   If you leaned on wiring, sensors, and/or connectors while changing the oil, you'll have to check all that to be sure pins didn't get pulled out, connectors broken, etc.. Old wire loom that was barely adequate when new is certainly brittle by year 19 - make sure wires aren't chaffed and shorting out somewhere where you might have leaned. or supported yourself on it.   If your a mechanic, why didn't you just find out what you were missing and troubleshoot from there??  TIMED spark, fuel PSI / injector pulse, air, compression.  Can't make ANY money going the parts cannon route.

      LOL! Are you joking?? That wax SUCKS! 100% gimmick made to "look" good.    After just TWO winters I had severe surface rusting in patches over 90% of the frame. Only reason it looks great in the pics is because I SATURATED the frame every single fall with used motor oil for 14 of the 16 years I owned it. Otherwise it would've been sent to the crusher 8 years earlier with the speed it was rusting prior!    I sold that POS 3 years ago. Was a gigantic headache the second it rolled off the showroom floor. Brakes pulsated on the TEST DRIVE. Door trim fell off the 1st week! Interior squeaked and rattled, and the drivetrain clunked after 2k miles. 4x4 switch failed shortly after. Front end - ball joints, struts, hub bearings - all failed between 38k-50k. Engine started burning oil at 50k. Rear and and transmission failed before 100k. Nothing but problems, and frustration with the piss-poor engineering designed to make you give up. Well, it worked! Nothing on that truck was easy to remove ... except the wheels. They haven't figured out how to screw that up yet. Give 'em time ...   I won't make that mistake again. EVER.   Such fond memories ... https://postimg.cc/K1qf23tS  https://postimg.cc/gallery/X02z64J  https://postimg.cc/gallery/mHSRXZv  https://postimg.cc/gallery/D4mMRfL

      OBD not ready?

      By davester · Posted

      Different monitors do their test only under conditions specific to that monitor.  you MIGHT find the drive cycle conditions for the monitor that isn't ready on this site: https://lemon-manuals.la/   If it's not there, then it should be on alldata.com for your truck, but it requires a paid subscription.   And you need to know which specific monitor isn't ready.
