two questions
first off... i finally got my FD back from the shop. now im back to troubleshooting my boost issue. here are the symptoms....
first start-up and run on a cool night... pulls good through all gears. after a bit of driving though she gets real sluggish coming off the light. almost as if im towing something behind me. boost pattern is typically 11-7-5. so could it be a clogged cat-converter? or a bad CRV?
second question... will my G-force ECU be able to handle a DP MP cat-back exhaust set-up with out spikes or creep?

Question 1: With your boost pattern like that there is a HUGE possibly if you still have stock cats that your cats are clogged. Get a DP and Catback if you plan on getting a midpipe port your wastegates.
Question 2: Port Your wastegate and get a manual boost controller to avoid spikes and creeps...

thanks... ive been suspecting the cat-converter for awhile. its actually a high-flow type, but i dont know the brand, and its been on the car since before scott tessier (previous owner that sold it to me) bought it. i have no idea how old it really is.
my wastegate is ported, and i have a full exhaust upgrade. how much HP and TQ will i lose if i put an old stock cat back on there untill i can find a good replacement?

The Stock cat back is quite restrictive you would probably "guesstimating" lose about 10-15HP depending on mods and boost. If anything get a stock cat and gut it and run it as a midpipe it still offers a little restriction as it isn't as free flowing as a 3 inch pipe but isn't as restrictive as the stock cat.

From experience a friend of mine ran a DP with gutted cat and N1 catback and experienced no creep but all cars are different get that and make a home depot manual boost controller....solves ALL your worries
