is this product any good? pros/cons? I've got a stock '99 z28 with slp lid and (cringe) flowmaster 80 series muffler. thanks for your input guys.

 

For mostly stock, yeah you will get a little more and can adjust for gears, tires, rev limit at will. A little pricey for all that and will not do any good once you get headers or other mods. But, I just sold mine for $175 on ebay so deals are out there. If you do buy used, make sure it was deprogrammed on the original vehicle or it will be useless.

 

ya, I was on the ht website and it said the programmer is 'married' to the original car it was used on and cannot be used on any other car... of course they would say that but I was wondering if it's true or not..

 

will let it go for 175$ you pay shipping. interested email me..

 

not exactly ...it's married as long as the hypertech tune is in the car but when you program the car back to stock you can use the programmer on another car.."one car at a time"

 

I'm interested but can you tell me what you think of the thing? as I say my car is basically stock except for the lid and flowmaster. will there be any noticeable difference with the hypertech tune?

 

Yeah you will notice the difference .. I paid 300$ for it new that is not worth it "my opinion".. but I say 175 is a steal. My car was stock except exhaust and I ran 13.80 @ 101mph with the tune in there. You can adjust shift firmness, shift points, gear ratio's, the engine tune for 93 oct or 87 oct, desired fan temps for low temp tstat, and now Hypertech makes a card for it to read trouble codes and clear the as well.. Go on their web site and read up on it.. Let me know via email and i'll give you my # to work it all out... BTW I have a set of BBK mid length ceramic coated headers to

 

NEVERMIND I THOUGHT YOU HAD A 96..IT WONT WORK ITS FOR LT1'S

 

You will notice a difference, especially if you add a 160* therm which I recommend. Not huge, but I could always tell when the tune was there or not. Just understand that if you do any more than CAI and catback type of mods you will not be able to use it. HT says that up front on their website now.

 

I really don't understand what difference a 160* stat will make, since this only affects the car during warmup. once the engine reaches operating temp the coolant is always over 180* and the thermostat is always open anyways. I could be wrong but it seems like this is just another gimmick for people who don't understand how things work.

another thing is I've read some horror stories about the HPP actually making the car run worse, knocking and idling rough, which I don't know whether or not to believe.

 

Because then you can take advantage of the fan reset. My temp never goes over the 180 mark.
