look in to the DHP they seem to have thier heads in the right place.
I have not been ompressed with Hypertech,
they made the sale and there for dont care i guess.
It is a shame it could be a great product if the would ave folks that were worth a crap behind it.

 

Well I talked to the guy who sold me the Hypertech on Ebay, he's been really good about working with me, he told me to just send it back for a refund. So thats a relief. The DHP maybe the next option. But I have to buy the downpipe to go with my Corsa exhaust.

 

I wish they could get a clue tha thte LS version with the 3.4 is moded just as much if not more then the SS 3.8 version.
GM. seems to think if you have a lower pricedmodel you cant mod it.
bad enough all of it for both cars is limited.

LEt me know what ya end up doing on this I would really like to hear more on the DHP stuff. from others that might have it.
so i can hear thier points of veiw also.

 

Well I'm fooling around with 2 cars right now. I have my 2005 LT with the NA 3.8, and my g/f has a 2005 Impala Base Model with the 3.4 . My plan is to remove my exhaust system and put it on her car. She has a single exhaust, I want to give her my stock dual (plus U-Bend Delete) exhaust. I'm sure the 3.4 has a few things you can throw at it. My plan is to get a down pipe for my MC and pair it with my Corsa Exhaust thats in the mail, once I have them, pair them up install them on my MC, and then take my stock MC exhaust and put it on her Impala. We'll see what happens. Still my main issues is if the o2 simulator will work with a 2005 MC.

 

keep us posted on this. i have always wonderd just how close to us the imp eally was.

 

im not 100% familiar with onstar, but i'd assume is just like the GM scaners at best. they can only look for engine codes. and at the very most prob speed and rpm ect. it wont beable to read your computer file. not it prob would void the factory warrenty but how are they going ot know? they cant scan it to find out... all they will know is that the PCM isnt working as normal, they would flash the pcm back to factory specs and thats the end of it. you can then just use your tuner and put the file back in.... people are even adjusting settings in their cars so they pass emisions when their car would fail a sniffer test! most 96 and later cars they just run a computer scan for codes that would effect emissions, if you correctly remove these, no codes will show up even if the components arent even in the car... ect. my car had no egr, evpa, or air pump! not codes at all and scans as if everything was normal. the GM people would be stumped to say the least
