BUYING A 2005 SIERRA DENALI AND I WANT SOMETHING DIFFERENT WITH THE EXHAUST AND I AM TOYING WITH THE IDEA OF MOUNTING 2 40 SERIES FLOWMASTERS IN THE SPARE TIRE LOCATION, AND THEN AN X PIPE IN ABOUT THE LOCATION OF THE STOCK MUFFLER OR FURTHER UP. MY THEORY IS IT WILL SOUND SIMILAR TO A CAMARO OR CORVETTE, GRANTED BECAUSE ITS A SIMILAR SET UP. ALSO GOING TO DO LONG TUBE HEADERS. I WANT TO TRY AND GET RID OF THE TRUCK SOUND.. WHAT REALLY MAKES THEM SOUND DIFFERENT IN SOUND ANYWAYS? I SEE VIDEOS WHERE GUYS DO THE LQ9 SWAP IN A CAMARO OR TRANS AM OR CORVETTE AND IT STILL SOUNDS LIKE A VETTE OR T/A WITH A TRUCK ENGINE IN IT. ANY INPUT APPRECIATED! THANK YOU

well we changed pe mode, the commanded fuel setting way out of whack like .50 and 1.20 just to get a reaction from the engine and never changed after zeroed out all the other parameters. like somethin else is keeping it from goin in

zeroed out all those parameters and still nothing out of pe mode????

ya know whats weird is the damn thing shifts super hard in first and 2to 3 sometimes almost seems as if it slips sometimes... and tq management is pulled out of it, even when it was completely stock it was that way. any ideas on that ? im sure we can prolly tune it to make it work right but just wonderin if maybe that means somethin if its stock and acting that way.

also can i ask ya do ya think thats where a guy is gonna get rid of that lag off the line on this 08??

gotcha i will do that! thank you for finding that.

is there some hidden ones on the E38?? where should i set the map threshold? its at 15 kpa right now

any other ideas? does pe mode even activated in the 07 up silverado?? changed up all the enablers and got aggressive with the pe mode parameters and doesnt seem to be doing anything???

it is a 2008 silverado crew cab 4x4 3.73 gears. 5.3 flex. exhaust is only mod.

yes that was the case with the throttle position. what do ya think on the dead spot off the line...? sounds pretty typical of factory tuning??

doin some tuning w a buddy of mine semi amatuer at the efi live, tryin to clean up the dead spot on wide open throttle from 0-20 roughly. seems as when you hit the gas from 1700 rpm to 2300 rpm it has no grunt per say "dead spot". have removed torque management, and most of the disablers like traction control... any ideas what to do to clean it up? also seems as if the throttle position only opens to 83% at wide open throttle at all speeds i would think it should 100% at some time but looking for some pointers there. timing seems to be at 20 degrees advanced between 1700-2300 rpm. any ideas thoughts appreciated thanks

dont you do tuning? i know i bought a shift kit from ya a while back. how much to get one done for my 08

I HAVE JUST BOUGHT A 2008 SILVERADO WITH 5.3 FLEX FUEL ENGINE. AND I WANT TO GET IT TUNED. WHAT KIND OF GAINS CAN I EXPECT? AND WHO??

I HAVE A 6.0 AND WANT TO KNOW IF E FANS OUT OF 05 1500 WILL BOLT ON A 2500HD WITH 6.0??
