you think i would really need it with my N/A engine i building its going to have alot more compression then stock stock is 9.5: and i getting 11.1:
i really just want to make sure i getting good air fuel ratio

its also getting stiffer valve springs ported head polish valves jbp stage 2 cams header ho manifold port matched under drive pulley 2.3l oil pump conversion lightened 8lb flywheel stage 3 clutch and pressure plate

so the question is am i going to need hp tuner to tune this thing and iam just wondering if i could get by with out it or would it be a wise choses to get
some ppl that have built N/A 2.4l just give me your opinion


Thanks,
Paul

anytime you wanna make a high HP app tuning timing and VE will become a very important task. With the items you listed you will need some pretty exact tuning... I would say..



1)YES


HP Tuners | Garrett T3/T04B | 2.5" Charge Pipes | 2.5" Downpipe | 650 Injectors | HO Manifold | Addco front/rear | Motor Mounts | HKS SSQV | Spec stage 3 | AEM UEGO Wideband | Team Green LSD | FMIC | 2.3 cams | 2.3 oil pump swap | 280WHP | Now ECOTECED

From what I understand you can take HPT and use it on a stock vehicle and get improvments out of it if you know what you are doing. So I say yeah it would help.



My car has two speeds, fast and faster.

you may want to do some research on the flywheel.

if your not making enough low end power, your going to rev right thru the power band.


...

That big of a compression change, oh yea your VE is certainly going to change



1989 Turbo Trans Am #82, 2007 Cobalt SS G85

i had the lightend flywheel on there before the the engine went.
so i will be putting it on with my rebuild.i really dont think there will be a problem.

i was doing some research today and iam just wondering for the hundred dollars more i might as well get the advance version rite?
what benefits do you get for the advanced over the basic.

Thanks,

There's a whole FAQ in the tuning forum that tells you what the differences are, and, if all else fails, you can read thier website.
