The Official Dyno Thread
You imply the car stock vs stock program with modifcations will make same power....that is not the case. Learn down is simple air load values you can not pass (that is in gms1 still)....stock the car with mods made 10whp more then completely stock cars, with higher airload values it is now 11whp higher then the only other gms1 I've seen with dp...the ecm has never tried to maintain a certain whp number
look at how when the dyno hits 260 trq it just keeps bouncing off of that.. the same way it wouldve stockat like 240-260 ( depending on dyno) the desired airload value doesn't move up at all so there would be no way to continue to show gains from mods without a tune.. vendors have shown this

what was your first dyno with the TVS? no meth and 91 pump gas?
thank you. you can see it's only at 6500, and it's rising sharply right when he let off. that was on a base TVS tune. since then i have dialed in the maf, and cleaned up a lot of the drivability portions of the tune. i am anxious to get back to the dyno...

oh boy... where to start?
TVS with 2.7" pulley, ported intake manafold, dual pass with opt B, ZZP H/E, OTTP 3" intake, CTI header,3" CTI catless DP, and 3" CTI catback, 80lb injectors, OTTP return fuel system with modded walbro fuel pump, E-85, 1 step coolder NGK sparkplugs, sparkplug spring inserts, MRZ light weight crank pulley, SPEC stage 3+ clutch with lightweight flywheel, custom tune by OTTP, STOCK ENGINE!!! NO HEAD OR BOTTOM END WORK!!! Mods comming this spring - OTTP fuel rewire kit, possible LS4 TB, poss built engine!
I think that about covers it, lol
note that that dyno graph was with an off the street tune, and i was running a full point lean at the top end, i was told with a little tuning which i have had done and some better airflow (driving vs boxfan) i should easily be past 350whp. havn't had it redynoed since i got tuned!
