the other day i ran my car on high boost for the first time 15psi on stock tt , now 2 days later on normal 12 psi that i run it has a loss of power and sounds like it is looking for it. i just cleaned my air filter and checked for clogs didnt find any. im putting the airfilter back in tomaro but does anyone have any ideas of what it could be???

 

How different was the temperature outside on both runs? I'm wondering if the high (if you have the stock ecu and are boosting to 15 lbs, be very careful. Seems to be a recipe for BOOM!) boost you had was on a cold day where the air density was so low and the IC so effective as to give this high a boost?

 

no i have a pettit unlimited ecu, but both days were about the same temp 35 degrees F.

 

can you share some details fo your setup, you coudl hav bvlown a coupler, etc, blown an engine, etc. how does it idle? how is teh vacuuma s compared to before? pull your plugs as well, at 15lbs plugs don't last very long especially if you are using the non-platinum.

 

Could be a boost leak. That happened to me when it ran at 14 or so psi when my norm is 11. The stock rubber vac. hoses weren't used to that boost. My car currently isn't as strong as it used to be either after i took it to the drags. After I took off the stock intercooler-to-throttlebody tube I saw a TON of oil

 

well i took it for a ride today and it has a hesitation threw out the power band starts at 3k all the way to 6-6500rpm. car idles fine , has 20 on the vac as usuall. just now doesnt brake loose in first like it used to at 12psi and has a hesitation pretty much in every gear. maybe some sensor? i have ngk plugs and msd ignition but i dont know if they are platinum

 

what is your boost pattern now? if your boost pattern is spot on, check ingnition stuff, ie plugs coils, etc. also you coudl try checking water thermosensor, etc. I had mine go did some strange things.

 

my boost pattern is fine. i noticed yesterday it only starts to hesitate at wide open throttle. so long as i dont floor it it doesnt hesitate or give me the diffrent sound. going to look over the ignition tomaro.
