I'm wondering if you guys have done any tests with Pypes X-Pipe Exhausts and how they handle the LS1/LT1 if you have?

Not much really... one or two with the Texas Speed duals w/ X... wouldn't say they are any higher than a good y-pipe and catback. For the street, I'd stick with good quality headers, a y-pipe and a Magnaflow catback for the best performance. For the track (occasional street), duals dumped before the axle...

i have a 2002 ws6 trans am, next to the tcs button is a little red switch, when you flip the switch up a little red light appears on the switch, i would like to know what this switch does/ activates
thanks, adam

Sounds like someone added something aftermarket - could have been nitrous, or a linelock or something like that. Might have taken whatever it was out and just left the switch. You could trace the wires and see if they connect to anything...

Altitude changes with a MAF tune???

Tuned at 5400 feet.
Seriously thinking about running at 600 feet soon.
Large hydraulic cammed 402. MAF Tune.
What might I need to change before leaving? Would the MAF pick up the difference?
I am thinking it would, but go a little fat.

The MAF will see the difference as long as your tuner didn't do anything stupid with the MAF table... that's why its important for a tuner to maintain the slope of the MAF table even beyond what they may be tuning at the moment - colder temps and changes in altitude will put you higher up on the table. Most know that and tune the whole table. There are also calculations within the computer that take into account barometric pressure changes through MAP readings. You should be fine...

I have an odd question for you. So, i've rebuilt my 3.8 more times than I can count now, and have a 'few' different combos with cams and such, but im still with the CompCams GT2 Roller Cam 216/216 .507/.507 111LSA, as I prefer the powerband with running the shot of nitrous I have. Anyway, back to the subject at hand.

Two rebuilds ago, I had it dynotuned, without the spray and with. The tune I did that time I was running a stock exhaust manifold. I dyno'd at 298rwhp/240rwtq. (All tunes done at same location with same tech) Im a tech myself, but I hardly know how to use the software they're using and am unsure of somethings they are doing.

Since then, the motor has been rebuilt with all the same components except i've added pacesetter midlength headers and swapped out my gears (4.10's to 3.73's) but after the last dynotune, I dynoed at 270something rwhp but nearly identical rwtq(cant find my sheet right now).

I've checked most everything I know how to sparing taking it to another dyno shop.

I am wanting to put a 160 degree thermostat in my 2002 WS-6, in the future I want to add a new Cold Air Lid and box, 85mm MAF, headers and cat back with new converters. Nothing too radical but I noticed SLP has a full kit out there with a reprogrammer for 375 horse. If I were to add the parts as money allows, what is a good tuner to cover all of the additions or do I just need to sit on my money and do the package deal?
