I passed up a great deal on one a few years back, wish I didn't know.

How does Gearheads tunes work on your truck? I have not towed with them yet but boost seem to be up and he commented that he sees low boosting truck regularly. .

His tune is nice, I pulled with it over I70 and it did great. Nice power band. I've only got about 500 miles with his tune.

Agg tow or unlimited.. I will try and pull my 17k lb with his agg file.

With my setup on a tow tune, if I go wot from 15-95 I will see egts around 1400-1500. My boost will hold 25-30psi the hole time too.
I think it would be his agg tow.

To op...no gain. 5in is sound only.

I talked with quick tricks and will have my 5" exhaust in October. Hopefully I'll have time to put it on before I go to Texas. I'll post back when I find out if it changes anything.

I went fcrom a 4 inch to a 5 inch at one point. No difference whatso ever in performance. Actually, I preferred the sound of the 4 inch. Should have got another Silverline :doh:

Final got the 5" on, and live tuning down. Got my egts even lower. This summer I will load the old tunes in and see if the 5" helped egts or if it was all in the tunes.
