Re: SCT 100hp or lss ???
I can only talk about my stock 2004 with a 03 built engine. I use the SCT's Tow flash all the time and tow a 10K pound trailer every once in a while. The truck has 34K miles and has never "puked" coolant. Yes, some coolant has been released from the coolant reserve but it has never gone below the Min line. About a month ago I added 32 oz. of coolant just to bring it up to the Max line.
A week ago I flashed the truck back to factory settings so I could trade the Xcalibrator for version 2. This weekend I towed the trailer with the factory flash and it felt like the truck was neutered. I immediately felt that some power was gone. While towing the EGTs went over 1,200 for a while and they have never been that high when towing with the SCT Tow flash. I got the gauges after the SCT so I don't know if the EGTs got that high before the SCT. I also lost about 1 MPG in daily driving and about 2 MPG when towing.
So, is the SCT safe? In my case it is. No coolant puking, no transmission issues, better mileage, and lower EGTs. Your mileage may vary.

After all the quesions you have asked about modules/tuners your truck is gonna be worn out by the time you actually buy one. /ubbthreads/images/graemlins/smirk.gif

I run the SCT tow tune daily. I tow #5000 2+ times a week and never spilled a drop. I do have questionable EGT at times and I see 2 MPG increase when I drive "normal".
I too switched back to the factory tune because the XCal 2 came in. I drove around and tow'ed 350 miles to San Antonio and back this past weekend, I miss the extra umph and tranny shifts the tow tune offers.
From what I've read on this board, it's got me scared for sure. I've spoken to the SCT dealers and they have very simliar remarks - that their tunes are mild.
