Turbo In + Crusing + Partial Boost = Overheat?

Turbo Out + N/A + Full Throttle = Doesn't overheat?

This is my third turbocharged application and this is the first I have ever experience this.... Now to the questions and my brief story!!

Alright, I got this weird problem. I had my turbo kit in recently. I have a d16z6 with vitaras, eagle rods, kms blockgaurd, cosmetic head gasket, arp head studs, dual core delsol radiator, drag manifold, 38mm tial waste gate, large 6 inch johnny race car inter cooler, turbonetics t3/t4 to4e hybrid, thermostat w few extra holes mod. Anyhow, my question is why am I overheating just cruising at light throttle near 0 psi and into boost? Could it be the intercooler blocking air flow? Could I my timing be too advance? Well the part that gets me is I took the whole kit out and I am N/A until this is solved, but the weird part is that I am no longer overheating while I am N/A 0 to 100% throttle. Why is this? Thanks any help will be appreciated.

It probably has to do with your timing.

yeah, i will look into it. i basically did a swag on it because i had no lower timing belt cover, so I couldn't do my timing properly. i will keep you guys updated. i was also in in between 11 to 12.5 afr

ywho tuned the car please tell me you didnt just put the kit on the car an driver also you could be facing a number of problems
1. timing
2. fuel
3. inefficent intercooler

A turbo is going to put out much more heat then a header, that coupled with an intercooler blocknig airflow to the radiaotr is most likely causing the overheating issues.

is there a large gap between your intercooler and radiator? i just read a thread on here the other day, it seems the smaller the gap the better between the two, ie <1"

The intercooler was flush to the chasis their was really no gap. I cut my bumper out in the shape of my intercooler. As for tuning wise stuff, I was running a SAFCII, an LC-1 with a moates O-meter, 450cc blacktop injectors w/ inline resistors, walbro 255lph fuel pump. afr stayed around 14.7 crusing light throttle. and around 11.5 to 12.5 hitting boost. I would say that I was pretty rich. I am guessing its a timing issue that has to do with the SAFCII. Hmm.. I think I just figured it out. Well next system I am gonna go with is crome pro.

there ya go no timing adjustments being made
