dyno wierd

well ambient temperature has a lot to do with it....if its hotter outside, the hotter, less dense air will result in less power, compared to the colder, more dense air.
Also, wheel/tire size will affect the power output while on the dyno.

im on teh same wheels and same dyno with the same tuner
does that mean its better to tune the car on a cooler day..my tuner said that its better to tune on a hot day so u can get the worst case scenerio..As the temp gets cooler, the ecu will correct itself

hot air is less dense which yields less power...think about it...cold air intake, intercoolers, intercooler coolers, dudes icing down intakes, hondata intake manifold gaskets
cooler air more power...tune on a hot day and get the most out of the engine with hotta air...in theory when its cooler the results will be better

well just like your tuner said that as the air gets cooler the ECU will correct itself, the same applies for when the air gets hotter.
This is the nice thing about using a honda ecu for our tuning needs....it has IAT and ECT corrections, that don't need lots and lots of manipulating to get the car to run well under all different conditions.

but does my dyno reading sound normal for a b20 z vtec, type r cams, megan header, type r intake manifold, type r tb, prelude injectors, walboro fuel pump , j's racing short ram intake, omni valve springs, omni retainers, str cam gears, unorthodiox pullys, no power stearing and no air condition ,2.5 inch crush piping, magna flow, high flow cat, and a no name twin loop exhaust. i believe it has 2.5 inch inlet
and obd1 dyno tuned

see thats the problem with b20vtecs....the b20 pistons have very small valve reliefs (compared to the vtec pistons). So if you have cams with lots of lift or simply too much overlap, or the intake valve opening too early you take the chance of smashing the valves with the piston.
A good header, like SMSP, RMF, Rage, Hytech, F1 racing, etc etc will get you more power than any off-the-shelf header will....but good headers are expensive.
