TT Chip mods for Alcohol

[Mr86t-type]

Eric,

Last year (1/07) you made me a Stock Injector (105 Octane) Chip with ~26degree timing thats been great, however I just installed Razors Kit...and it's Great, but for Even Better Performance, Do you need to Pull fuel out??

No you shouldn't need to pull fuel with stock injectors unless you are running the boost real low. You may have too much timing though, especially in the midrange, so watch out for "transitional" knock.

? for Eric

Eric, since i installed the TT Alky chip i get some popping through the exhaust when i let off of the accelerator. This is when in Drive and just cruising. Do i need to trim fuel in 3rd gear? or is this caused by backpressure maybe? any suggestions would be appreciated.
Thanks,
Chuck
