GT350 Intake Dyno..ENJOY!

[RubyRedBoost]

It does it at full operating temp. It's not really a huge deal as I feel the benefits outweigh the negatives. Now cold dense air really aggravates it. A quick downshift usually gets it back on track. I've only experienced it in the 2-4K range during partial throttle and tamer driving. If you accelerate a little heavier it's almost non existent. Which I do most the time unless my wife is with me.

Hmm that's really interesting. Mine (not Lund) doesn't surge outside of warm up.

My Lund tune has no surge at all no matter what the temperature.

What throttle body are you using? I have the gt350 tb

GT350 TB here as well. My car was the one Lund used to test the TB. Jr had my car in his possession for 2 weeks. Not sure why that should make a difference because I would imagine they are sending out the same tune file developed on my car for every one else with the TB.

I'm running the newest tune from Lund with the GT350TB. It's still has partial throttle surging but nothing like what it was. Throttle response is crazy compared to the stock tb though. Was told this is about as good as it gets. If Ford has this dialed in I don't know why Lund doesn't copy the tables from one of the power pack tunes.

Would'nt that be copyright infringement?

09jsw's car was used by rev auto for r&d of the gt 350 tb he has no surging issues at all! Tuners just have to put the worki in to get it right!

Update!!

Here is the dyno pull from this morning comparing the stock and gt350 tb on identical tunes with timing locked at 27 degrees

the lines overlap, mind you my "stock" tb is ported so take that for what its worth...also these are the best pulls from each.

If it is copyrighted then maybe Idk I'm not a lawyer. I meant examine throttle tables not the copy whole tune. You'd be surprised how many products are reverse engineered.

If you just need a quick upload, try: http://tinypic.com/

It won't be hosted forever, but I too ran into an issue with Photobucket. Idk what's wrong.

thanks man, trying it now

wow very little difference between the 2..interesting so if you have stock valves cams etc. you cant go wrong by using the stock tb with an adapter.

this also leads me to believe that if you add cams bigger valves upgraded valve springs etc.. you will likely benefit more from the larger gt-350 tb.

Thanks for posting this!!!

 

[sandeale]

No problem at all, and I do believe once cams are added that the added airflow potential should be beneficial....but on a stock cam car the tb is just bling factor, although the throttle response from the gt350 tb does negate the need for a sprint booster type signal manipulation device, so the cost balances out

 

[newkidnik]

Weird! Thanks for taking the time to add to the knowledge base for this part.

I'm reading correctly in that the GT350 TB loses some power down low? Would some tune massaging correct that and maybe add power over stock?
