Hey Justin!

Hey, I've been reading a lot of your posts and Im going to go ahead and get a tune from you. I am waiting for LS1 fans I got off ebay and underdrive pulleys, would It be alright to log the data without those things? Or should I wait until I get them installed, as of now I have a K&N Intake, TB Spacer thats nothin, and true dual exhaust with glasspacks, The middle of next week I'll be getting in touch with you...Can't wait. Thanks.

My trucks a 99 GMC 4.8 Auto 4x4 Reg Cab Short Bed.

bump...?

you should be fine logging it now

Alright I appreciate it, after searching and reading for a while I found that he can just activate the pin on the pcm to accept the fans when installed, does that sound right?

Yep, you should be fine. Justin sets the PCM up to control the fans so when you get them, you can install them and they will work fine. As Mike mentioned, you'll be good to go ahead and log your truck now as well! You won't regret getting one of Justin's tunes:anitoof:

Hey Shawn,

Mike and Matt are right. You can have it logged before with no problems. When do you plan to have both the fans and pullies installed?

The fans and pullies are gonna have to wait for summer, or until i find a shop I can use...The PCM Swap I can handle in the cold but getting involved with the pullies and fan stuff when it dosent get above 0 sucks pretty bad. I'll be getting in touch with you friday the 1st, or monday the following week if your available. Thanks Again
