I installed a 1.15 non wastegated exhaust housing on my turbo. My egts are now higher than the were before, my boost comes on slower than before, it will still get as high as before but i've really got to be into the throttle to get it there. It seems to have less low end but better power pulling a load at 70 mph than before but again the egts are about 150 degrees higher. Ive been told i had a boost leak somewhere, i've looked at everything, it all looks like it did before, so is there a good way to find a leak if there is one. or does anyone have any ideas why the increase in egts instead of the decrease i was expecting. thanks

Also would it be better it put the stock compressor wheel back in or leave the wicked wheel in? any input would be great, thanks

You can build a boost leak detecter

Well that is what happens when you go to a to big of a housing. Bigger isnt always better. You have to have what fits your setup and a 1.15 housing is WAY to big for stock injectors. I'm running a 1.00 on my 38r just because a 1.15 would still be to big for what i would like. They spool a lot slower and dont produce the boost because they are bigger.

The turbo being too big for stock injectors explains the slow boost and lower boost, but do you have any ideas on the higher egts?
