More Power......
I Use A Hypertech III On My Z. Are There Other Tuners That Deliver A More Noticed Power Gain? If So - Which One(s)?

most people agree that handhelds are not the best for power. They are pretty limited in what they can do. - fan temps, gear ratios, shift firmness. There was a guy on here who dyno his car with and with out his hpp3 and he actually made more power without it. lol
I wouldn't spend any more $$ on a handheld. A dyno tune is about the same price and you get a lot more power!!

I had a HPP for my LT1 and didn't see any gain at the track or on the street. It will help your shifts in a stock automatic but I had a stall and shift kit. I would spend my $$ in something thats going to add more for your money. A dyno tune would be the best way to go and you will have the paperwork to back it up! But thats just me.

Thanks for the input. I noticed a slight lag from 0-30 but then it seems to come alive better than before. I think a set of .342 or even .323s would really help my low end as opposed to the stock .273s. I too think it was an over-hyped waste of money.

the hypertech handheld only allows you to change about 10-15 items-Whereas a full blown tuner will allow you to chage any of the apprx. 500 items.When I do a basic tune with EFILIVE change about 100 to 125 entrys on an automatic and about 75 on a M6.That being said GM didn't leave a lot on the table anyway on the C5 and the Camaro/WS6.Typically I can realistically gain only about 15-20 RWHP on them. On a truck or SUV it's different. There is alot more you can get--approx. 25-30 RWHP.With an automatic however, you can make it go alot faster without increasing the HP at all, just by tweeking the transmission and TCC tables.I would estimate about a .40 second increase in the 1/4 mile
