rx1 problem

[jackal]

hello to all! my turbo rx1 will go like the wind until 9000rpm then i have to burp the throttle a little, once it gets to 9500rpm it clears up and once again runs like the wind.any ideas would be greatly appreciated. thank you

Likely hitting a lean spot in midrange if this is a new install. If it ran good before, you have a boost leak. Usually leaking tees or crack in connections under tunnel if a rear mount....


There are some good black turbo carb springs that help eliminate his issue if it is lean spot.
