i found a local tuner that is using hp tuners to the tuning setup. IS that a good tune for performance.

Hp tuners is a great tuning tool, but what you get will depend on who's using it If He/She is a tuner who is experienced with LS based engine management, you should be just fine.

DOUG @ ECS

well said, HP tuners or EFI live are just tuning tools, the deciding factor is who is typing the key board. It's not like a hand held that just down loads a basic tune.

HP tuners is the only way to go..get someone that is good..

Why?

2MuchRiceMakesMeSick

HP Tuners is just a software package used for tuning.
The quality of the tune will depend on the person using the software.

Its like asking, is a z06 good for autoX. Of course the answer is...depends on who is behind the wheel.

robert miller

can do as much harm as good. are be taking it back to them again and again.... can lien a car to much on top end then you have blown motor. to rich then to much gas in the motor. just for 1.

Sorry I think I need a translater for what you are "trying" to say. You said a specific tuning software was the only way to go...that is what I was asking "why" about. Why is HP Tuners the only way to go?

is a wideband necessary to tune these when not on a dyno for a/f readings?....Ive been borderline EFI live/HPtuners wish i knew which one was easier to tune with and which one was more capable

Yes, you need a w/b. Without one you're just guessing on the AFR at WOT. If you guess wrong, BOOM. $200 for a w/b vs. $xxxx for a new engine. Not a hard decision. Either EFI or HPT is a good choice. I use HPT.

Kurtomac

where you guys putting these widebands in your car and where are they getting the readings from....one of the rear bungs not being used or do you need one on each pipe so its getting readings from both banks?.....sorry tuning retarded here

Billf6531

For tuning, just put it where one of the narrow-band sensors is, or weld in another bung in front of the cats if you want to run one permanently.

For a Na car you do not need a wideband to tune the car IF you know what your doing.If your a first time tuner then yes you should have a wideband.Of course it might be alot cheaper just to pay a tuner to do your car instead.

Kurtomac

then it gets expensive when i tune after headers and CA....then a tune after a cam...then after heads...then after the 92/92 combo...tuners charge an arm and a leg to do it

most give you break on price, after the first tune, the first tune is what cost them money, becuase they have to register your vin #

I have used both HP tuners and EFI live, there are good thing and bad things about both. I think HP tuners is easier to use but I like some of the scanning that EFI live has.

If the truth was known, a-lot have just coping some one,s tune and hitting you up for 400.00 are more. If it is not a really known shop I wouldnt do it any more. will cost you more in the long run...
