I'm have some problems with the LS4 tb goin back to the stock one and goin back for more tunin on saturday.

 

wtf is with all the low dyno #s for the tvs cars lately? < 300whp hardly sounds worth it.

What pulley are you using?

 

80mm but ls4 tb isnt workin out im losin power with it.

 

im thinking that same thing, im still paying my tvs off from the group buy....making me second guess getting it. I know its all about the tune but damn. So to the OP would you not recommend the LS4 and 3" intake?

 

280/240?? Hummmmmmmm

Yea, they are really tricky to get to work properly. Most people tend to stick with the LSJ TB.

 

goin back saturday for another tune with the stock tb it should hit 300. the car doesin really have that much tuning rate now.

it sucks i hate it.

 

AFR and Timing??

 

who know wat the afr it wasnt readin rite. there is 15% more fuel then my other tune. he did put any timing.

 

280 hp on stock head and cams is impressive to me, how much boost you running with the tvs?

 

I am going to make some suggestions for you. Get methanol injection and hptuners and then you will be set. If you don't know how to do the tuning yourself people can send you base tunes or sell you "canned" tunes so to speak over the internet that you can load onto your car.

I see a lot of people getting dyno tuned and the car is not making NEARLY the amount of power that it should and the tunes are crap. Is your tuner using hptuners or some no name program?

With meth injection your going to be able to push more timing and these cars love timing. If your on the stock timing map that would explain why your not putting down a lot of power. I am on the m62 and putting down the same numbers but more torque.

Ask your tuner how much timing you are running and let us know.

 

loose the megan, get opt b, get a h/e. Throw more timing it and lean it out slightly and you should be closer to that number.

 

20psi it had to unplug the boost bypass silinoid b/c it was hittin 15psi an the drop to 10 at 5k rpm

 

Nice Jared. She's got more in her. But, probably not as much as mine

 

wait till saturday im goin bac to smg

 

you're easy...
I got 282/281 with a M62

 

I put down 287/262 just from swapping over the tvs from my m62. Tuning and timing will get you past 300.

 

im going to get mine dynoed soon... running quite a bit of timing as well.... will there be any noticable differance between 5gph meth nozzle and a 7gph?

 

well then whats everyone doing wrong? if i dont put down atleast 320 whp im going to be so pissed off.

 

Didn't thru tell you the ls4 would cause problems?

 

you'll be disappointed at first....keep at it, it'll come.

 

If your on the m62 you are not going to get to that number unless you put a **** ton of work into the car.

 

Think if it like tuning for 60# injectors as opposed to the 42's that come with a stage 2 kit. A lot of things are skipped over just to get it to work, instead of figuring out where the engine/blower combination is most pleased at. Obviously, that depends primarily on pulley size if cooling mods aren't part of the equation just yet. Once you find the happy spot, you push on from there monitoring things as you go. The amount of time spent dialing in things usually determines how hard and how well it runs. It's an animal that needs to be respected, and patience has to be a part of the process. You won't get far without it.

 

nice jarad..but im still faster then you and im stock with tune

 

u might have more power but u cant drive 13.7

 

OOOOOOOO! lol

youll get good numbers out of it just be patient, freds good
