What gains did you see when only upgrading the bridge?
I upgraded my factory Y-bridge to the All Seasons Y-bridge practically as the last upgrade in the charge air plumbing, I just finished the charge air plumbing out by ordering an HSP hot side pipe to work with the vgt72 and until I get an engine build goin, or a set of twins, everything will stay like it is
I already had done a full egr delete with 3" cold side pipe, intercooler and manifolds, uppipes, turbo charger upgraded to a vvt4094 with 3" downpipe and built trans efi-live tuning
That being said, it made a very significant difference in a couple ways
1) I saw less soot in the exhaust stream
2) I noticed better throttle response in any scenario
3) after the install I saw a few more lbs of max boost, I'd be lucky to see 38-40psi before, after I've seen a consistent 40-42...???
5) placebo probably, but the exhaust sounds crisper to me now
6) I actually had a 1.2 avg mpg increase after this mod, srsly...but I'm pretty sure the stock y-bridge had been leaking, and it was popping apart under boost, which is why I replaced it
I didn't see any significant difference with my egt's, not that I was looking for it but my egt's seem more stable and the spike is less dramatic
I typically only pay attention when they're hot anyways...
This mod really seemed to tie the others I'd made in the system together, I'm not sure how it would perform on a untuned truck, or as a stand alone mod...
