Car low on power any ideas
For the last 2 weeks I have been pretty pist off with my car cuz its runnign like ****. I cant find out whats wrong with it. The car feels very sluggish and def not running right.
Here are my mods: my car makes 335whp on pump with a dynoflash,
MR BOV
TXS Catback
TXS Downpipe
TXS Test Pipe
HKS RS Intake
Ultimate Racing IC Pipe Kit
Blitz SBC ID Boost Controller
ACT Clutch (2900)
Walbro Fuel Pump
Greddy 660cc Injectors
HKS Cams (264i, 272e)
ARP Head studs
Last night to test everything out i did a pull with my freinds evo who has just an intake and full exhaust (2005) and no flash. Now from 40-110mph both cars were right next to eachother and we had to get out of it. I didnt pull on him at all!
Only simptoms i can see is the car seems to miss a little and boost doesnt hit as hard as it use to. Any ideas?
The only thing i have changed within the last month are my rims. I did keep the overall diameter though and i dont believe they are that much heavier than stock.
The boost is at 21psi and holds it fairly well till redline. I changed the plugs 3k miles ago and oil about 2k miles ago. I plan on changing both again tomorrow to see if the plugs are shot.

Today we changed the plugs and gapped them to .024. Took it for a spin and no difference. So then we did a boost leak test. Immediately we heard a leak from around the TB and so we tightened the IC pipe that connects to the TB. Tried the test again and still we heard a leak from the same area but not as loud. After further inspection we noticed that it was the TB arm that connects to the throttle cable that was leaking. If you held pressure on it, the leak went away. Is this normal? During testing we didn't hold down the gas pedal and the test was performed at 20psi. We are just running out of ideas. The car is still low on power.
Thanks

Do a compression check. Once dry and once after adding about an oz of motor oil.
If you get low readings, then add oil and they go up, you have worn rings. If y9u get low readings and they stay the same after adding oil, it's the valve seals.
If the readings are around 150psi, it's something else.
Air filter, Clogged injector, Slipping clutch, dragging brake caliper, and so on.
