Dynoed my car today
After getting a set of customorized pulleys and chip installed on the car last month and been feeling the increased the power on my butt dyno, I finally had time to do a dyno on the car last Friday to see the actul power gain. As you can see in the graph below, my baseline with a upsolute chip was 302hp and 298TQ. So i was expecting hp&tq numbers to be around 325 at least this time. However, the numbers turn to be quite disaappointing, 302hp and 308tq. I did realize the baseline was done at 64 F and 12% humidity. The second run was done at 79F and 36%. My dyno guy told me the change in temp and humidity accounts for around 15hp. but even take that into consideration, the power increase is low compared to other pulley&chipped C32s. I have seen other member's C32 get around 325 to 330whp with pulley and ECU. I have no idea right now as what's causing the numbers to be low. Could it be my intercool pump not working probably? Since March, i have been hearing this humming/buzzing noise from underneath my car. Any advice/suggestion will be very WELCOME.

What octane fuel are you running? If it is similar to 91 octane here in California then that might be normal for a hot day. Run some race gas with a near empty tank and you will pick up 20+ HP. If you are already running better than 91 fuel then there might be some intercooler issues.

Humming/buzzing from under car is covered in a TSB. Have your dealer look into it.

between my baseline run and second run, taking into the temp&humidity difference, i picked up around 15whp and 25wtq. it's bit low for a pulley&chip mod.

not stock.
no offense, but ive heard nothing but CRAP from UPsolute softwares....... I would try a relfash back to standard settings and ship the thing out to RENNtech here in FL...or something more worth your time and money.
Good Luck.

How many miles on the engine?
how many miles on the plugs/wires?
What altitude?
The is a tolerance on factory HP, so, it might 20HP, between specific cars. There may also be some variance on the dyno, but may be operator error. Some
model dynos, can give different readings.
If you do not have a real baseline, it is unknown, what you started with.
There are lots of possibilities.
Try running the dyno, with a big fan in front of the car.

don't worry about it. go to the track and see what numbers you do.
my c32 puts out the same numbers as yours and i have the renntech chip and pulley. but i have one of the fastest c32 times out there. so even though you'd like to see numbers on the dyno, in real life, dyno numbers don't mean much if they don't translate into a faster car.

but as i said, don't worry about the numbers until you run your car on the track. tell me more about this custom pulley and chip - as in who manufactured it.

Your car sounds like a stock C32, maybe a bit better.
