Sweet! Looks good Dewy! I just got back from California and trying to do some catch up here at the forum.......you gonna make it this Sunday? I should probably scroll down to the "Eastern" section and find out but i have to take the sections in order....

Update on the backyard mechanics...had issue with TPS not reporting 100% and Quik recommended elongating(wallering) the holes on the sensor...worked great.
I relocated my intercooler hoses a little too low in my engine bay and it appears to me my IAT's are tad higher than normal. Too close to the headers. I like them low(hoses), I am thinking heat shielding of some sort.
I put duct tape over the hole where the oil breather line goes in the TB being that I have a custom high tech catch can now. I gotta find a plug for that thing.
I also duct taped the intake tube oil pickup hole. LOL Black/Brown duct! I plan to get a different intake tube any way.
I have some switches and relays to finish wiring.
I can't get an RPM reading on my WidebandCommander unit. I have tried negative side of injectors, coils, and the white wire from the PCM. No clue how to get a RPM reading. Their techies are certain I am doing something wrong.
For race day I am gonna put my stock radix Hxr under the front bumper, it should be pretty ugly looking but very very very effective cause it will be 90* from the asphault. Not at an angle, just straight up and down facing the airflow, so I'll be running 2 Hxr's.
After the TPS fix, seems this morning it wouldn't go over 8#'s of boost. I had a max of 8.7#'s before the upgrades(on average). However, before the upgrade my boost would move around quiet bit (tenths), it now stays put, very solid and consistent. I am liking that.
I'll eventually do a inj swap tuning thread, but I don't know what I'll write up, it seems most of it so far is "experimental" and a bunch of BS tuning (IMO).

If you are having difficulty finding this type of source on your vehicle, you can use the negative side of the fuel injector circuit. This actually works as well as referencing the coil, if not better in some cases!
Remember, you'll still need to experiment with the sensitivity and RPM divisor in "Device Settings" to find the proper configuration.

redneck enough for you guys? I mounted the second Hxr directly straight up as I said I would. This is for track purposes only really, it's just not pratically. But I did test it on the road. If you stay at highway speeds, it keeps the radix iat down to around 95* (65* outside). At lights and local driving, 107*. Where it shines is IATs recover FAST! And with the extra liquid, take a little longer to start to get hotter.As I said, those headers under those hoses can't be good either, so i took larger heater hose and sliced it down the middle and put around the radix intercooler hoses. Then took regular plumbing insulating tube put around that. Then wrapped that in HVAC metal duct tape. (true meaning of duct tape). Kinda a trashy looking, but I bet it is pratical as hell.
