What is a "REAL" boost leak test?

[howslowcanyougo]

The real issue here is not nessesarly the leaks at the TB, and Injectors, it's WHY all of a sudden is the car slower and DSMLINK shows that I'm running so lean , 18/1 and the car is even slower?

This changed with ONLY the swapout of new small 20G and a install of a FMIC?

It would make sense that I have a large boost leak, that is causing the "false estimations" from DSMLINK right?

Guess the smartest thing is to nail down as many of the leaks as possible, and get on a wideband?....Or???

Also can you buy the M-300 unit without the display, and just dump the signal off to your DSMLINK?

And do you need another seperate "module" to make that M-300 WB O2 sensor work in narrow band mode?

What would you guys think between spending the $200-300 for a wideband unit or $100-200 for some time at the RS's AWD dyno/WB?

I know I should be getting both but, my DSM budget and my wifes tolerance is running pretty lean as of late.......;->

Or does Elite have a portable WB unit so Shane could just help me street tune and diagnose this pig, for a price of coarse?

Agian a Thank you both for the solid information!

Someday I'd like to get this A/T slug into the 13's!

If I had all the $ I put into this damm 2G A/T car, put into a 1G M/T, bet I'd be close to the 11's by now!
