AP Calculated WHP/TQ Accurate?

So I have been using my AP to monitor my car real-time since I've finished tunning it. How much faith could you put in the calculated values for whp and tq? It seems to be pretty good with everything else as far as I've noticed.

90 Octane, ETS O2 Dump+Race Test Pipe+V2 Extreme, Cobb 3Port EBCS, ETS Cold Air Intake, AMS Upper Intercooler Piping, Deatschwerks DW65c.

385/389

I'm going to get it dyno'd at some point too, so I will have a definitive answer to my question regardless.

AP Dyno is far off usually.

However the performance thing it has on it is pretty damn close.

I would focus more on trap speed that should tell you the whp it has.

yea, on 90 octane with those mods I would think you would be making about 320 - 340 on a dynojet.

Similar mods (plus a boost leak) I made 331/318 last weekend on a DynoJet.

Ended up making 310/277. A bad fuel relay started cutting fuel at around 6900 RPM or so. Gonna get a new one ordered up and then re-dyno. Dyno tech suspects probably 325 or plus minus 5-10.

Kind of a bit wiffed as to why my torque numbers would be so low though. Just from what I've seen, seems like a lot of people have hp and torque numbers within about 15 of eachother; not that its a big deal, but just an observation.

Not entirely sure, havent done an actual timed drag yet. We've only got one strip here where I live and they are only open for the summer (which I've been gone for majority of this one unfortunately). All their test and tunes have been on odd days too. Ill have to start practicing, id imagine low 12's (with my mods) from what I read around forums and here from other Evo bros.

Probably closer to engine hp/tq before the wheels.

The AP numbers are fairly close to flywheel HP & TQ. Therefore with an approx. 20% AWD drivetrain loss the numbers are in line with WHP/WTW #'s...
