I'v had my Greedy Intercooler for a few months now and I noticed that My boost comes on later than before... Full boost is at about 3-3500 RPM. Is this with the bigger intercooler? Also, How can you tell if your intercooler, pipes and hose are leaking. Is there a tell-tail sign???

I also noticed some backfire when letting off the gas... I dont ahve an AFC right now.. I only have the greddy intercooler, MBC, Helix downpipe and HKS Cat back..

 

Most of the time it is hard to tell if your pipes are leaking but on high boost while on a dyno usually you can hear a faint whistle or see that you can't hold boost by datalogging on a ebc or logging unit or some sort. Looking at your mods I think that you are seeing alittle pressure drop and slow spoolup due to the rich nature and bigger IC and proably warmer weather. The bigger FMIC will cause lower air temps so your fuel trim will be even richer than needed compaired to the stock FMIC, The warmer weather accounts for less fuel being needed and it affects spoolup as well and when you have a very rich condition you loose power and you also loose your spoolup because the air is less dense than in cooler weather. You need one thing to solve your issue. Fuel controler of some sort to say the least. Get a flash, piggyback or standalone depending on what your future plans are and get it tuned. You will gain 20+ hp alone. This is only my opinion, I am sure many other will have different suggestions.

 

right on the money

 

Sweetness.. OK.. AFC on the way.. cheers!!!

 

Pressurize the system to a couple psi over what you normally run. That will tell the story. Search on dsm boards for boost leak test.
