I will have data for the 3.4. Truck is at the Dyno now just waiting for it to get done. My only issue is I do not have a way to read iat2 since my truck was n/a stock. Going to get it back make a few runs, then swap to joels plate. Go back to same Dyno for a pull to get results on that, then back to the track.
If you are using any factory whipple midplate with a trick I/c, the way joels plate opens up for the trick core you should see an improvement. Not to mention he changed the height and reworked the flow pattern. Also the 2.3 midplate is a cast unit not billet like Joel's.
You do have a way to read IAT2, all you need to do is cut your IAT1 wires and extend them to the IAT2 sensor! Boom there ya go! lol
And let's be realistic, it took you 5 years to get dyno tuned for your current revision of mods from the last changes, you're really going to get the truck back after 3-4+ months waiting for this tune appointment, pop the plate on, and go right back? You've had months to get that plate on already haha
Few pics of the differences attached with stock midplate & IC next to JCC midplate & trick IC....
The plate is definitely worth it. There's several benefits to it...
1. the integrated IC spacer lifts the IC off the floor of the turkey pan, which helps reduce restriction in the lower intake.
2. the trick normally requires an adaptor to bolt up to the stock midplate, but it directly bolts to the JCC plate, which also helps keep the IC outlet off the turkey pan floor
3. the shape of the port was put into a flow program to improve air flow dynamics over stock
4. the size!!!!! this alone makes it worth doing the plate with the trick IC since you're blocking off some of the IC with a stock midplate. Use the full IC!
5. the boost/vac port is NPT threaded so you can use AN fittings and attach the vac/boost hose with something that won't pop off, like the stock midplate with a hose barb has been known to do.
