Prodigy Performance 3.6 Turbo DIY Install

[ducatidesmo]

Hey JL,

Been working with Pickles the entire time. Have it on and running for a bit. had a leak because I am a dummy and forgot to tighten the trans cooler.... BDA... Was FAST with the stock wheels, now just back to "Jeep Fast" with 37's and the stock gear ratio (3.73 for me). Next up is BRAKES then regear.

my down pipe is pretty darn close to the heater pipe no matter what I did, so I ended up getting heat shielding and I've been fine. Pickles and I now share an issue. Hesitation on, what feels like when the jeep goes from vacuum into boost. Rich condition, it appears to be.

Rubi with MT/Rs

Just had an interesting conversation at my local 4x4 shop. In not so many words, the shop foreman thought I was idiotic to go with a turbo instead of a supercharger. His thinking (because he has a turbo car) is that there is nothing until I go into boost... sure... if I was spooling up at 4000 rpm. I spool up about 2500... which will be right where the rpms are in 4wd LOW and 4:88.. Was actually kinda irritating. Always fun. Yes conventional wisdom, Roots/screw supercharger for low torque turbo up hi, I think that is going away.

sorry guys...stupid apple pics...

where is pickles? he should have the answers on this.

I sent several pictures via text message to clarify how things are routed on my Jeep, how much clearance there is between parts, etc.

The forum would have been a very inefficient way to try to communicate that kind of detail.

my down pipe is pretty darn close to the heater pipe no matter what I did, so I ended up getting heat shielding and I've been fine.

I still have no idea about this clearance issue. I have plenty of clearance on mine. The pipes are bent by CNC machines, then placed into jigs for welding. The process is setup to guarantee that every set of pipes is the same shape. I do still have an older set of pipes from a different supplier, though. I'll be installing a new set of pipes at some point, and I'm interested to see if I run into similar issues with the new pipes.

This seems to be an issue with the latest version of the tune (which also fixed other complaints I had). It's much easier to encounter this with a manual transmission, and happens for me around 1700-2000 rpm with attempted substantial part-throttle acceleration. With the automatic transmission, pressing the throttle a bit more will cause the transmission to downshift and avoid the issue.

I actually encountered this same issue on Prodigy's own Jeep (auto transmission). I met them down in Louisville for a weekend at the Unlimited Off-Road Expo and got a chance to take theirs for a test drive. They also encountered this issue a couple times while in Louisville, but haven't run into it again after returning to Florida. I've sent some data logs and descriptions of how I cause the issue to happen. They are working on it.
