Power problem

Hi !!!

I recently bought a gtir and i had many problem to resolve a lack of power. I think i solved the problem has 95 % and have the impression which the car is not yet has its full power.

I changed and repaired this:

- Sparkplug
- Fuel filter
- Oil and oil filter
- Prestone
- Cap distributor and rotor

- emptied the catalyst
- Changed the muffler
- look for boost leak
- compression ( 140-140-140-140)
- Leak down (corect)
- Turbo boost (ok, around 6 mm/hg on oem boost gauge and stable)

The principal problem was resolve. The muffler was completely stoped but have still the impression i don't have the normal power.

Sometimes, i beleive that he have his full power and other times not.

Someone have an idea of what could be the probleme if there is one.

ps: it's normal to do 150 km with 25 $ of super gas (1.44 $/L) ?
thanks

Someone have an

Try regrounding the maf. I'd use one of the diagnostic tools ( Consult) to see what all the sensors are doing. Have you checked ecu codes?

I put in a mines computer and its quite a different power curve from the oem ecu. Smoother, More response, more power, better mileage. I think the car should have come with the mines tune from factory.

Knock sensor?

first off do a fault code check..once that is done...make sure you are running a spark plug that is at least a heat code of 7...a heat code of 8 is required if you are running anything other than stock boost..
