I wanted to know if anyone has N/A dyno graphs they can post up. I'd like to see the variences of mods. Could you list them as well. Is there a link of what I am speaking of. I did a search and came up empty handed. (prob cuz they are all FI now?) I just did a few pulls the other day and my hp drops off at 5250rpms and my torque carries out until atleast 6k before it drops off??? The hp drops off as fast as it builds. It looks like a mountain top. Tq is somewhat flat throughout only 30rwtq variance from 2k-6k
This is the best pic I could. My camera would only do a close-up. My scanner isn't working. Any ideas what would do this? I have LT headers, JLT CAI, IMRC Delete's, No cats, thru catback, 3:73 gears. The first run I had a problem with IMRC plates and spark, so we tied them open. I just ran my car over the weekend and my numbers were roughly 15rwhp more because I put in delete's and cleaned up the gummed up valves. I left the sheet at the tuners shop...arghh but the curves were almost identical! Why is the rpm range so narrow? It drops off way to fast IMO???

Sorry for crappy drawing but the blue and red on the paper wasnt showing up so I just drew it lol. Hope it helps.

lmao..hey it works! See what I mean, your hp runs smooth right up to 6200rpms and doesn't drop off like a rock. My HP runs solid and right when it it touches the tq curve the hp drops off as fast as it was picking up. Could this possibly be a spark issue? My sensors didn't pick up any knocking. The tuner ran 23degrees at WOT on 93octane.

Do a full tune up and try some seafoam , then go to a different dyno that one thinks its JULY LOL maybe its only the machine.
