My 2.8 Colorado build with simple modifications

So I got my Colorado 2.8L 4x2 pickup last Feb 2017. It will primarily serve as my daily driver and shop truck for my shop, Profab. I live in the philippines so my Colorado has slight differences from the US market ones (mine is pretty much similar to Australian/Brazilian ones). Another thing I noticed is mine has no DPF nor 02 sensors. The truck is factory rated at 200 hp and 500 N-m / ~350 ft-lbs of torque.

After about 500kms, I started playing around with the tune via HP Tuners but of course was still conservative about everything since I didn't want to ruin this on just 500++kms. With the tune set, I was able to burn the tires at will on 1st gear and a bit on 2nd gear so I knew I had to upgrade the wheels and tires (stock was 16inch wheels) so I put on 18 inch Rays Gram Lights 57JX-6 wheels from Japan. Here's what it looked like:

After putting on the wheels, I decided to put in on the dyno with only the ECU and TCM tune and compare it without the tune to see my net gains since I have a couple of hours left after tuning 2 cars that day. Here are the results from that dyno session:

All stock, the car made 180 rwhp and 356 ft-lbs of torque at 1.1bar / 16 psi of boost. With the tune I did on the street, It made 215 rwhp and 418 ft-lbs of torque at 1.45 bar / 21 psi. At one pull I tried to do a 1.6 bar but the stock intercooler piping popped so that's a next mod along with an exhaust system in the future. I thought this should be enough since at this point the odometer was still less than 1000kms.

Another 2000++ kms later, I inspected the intercooler pipes were a bit wet with oil. So before upgrading them, me and my shop partner fabricated a simple oil catch tank with a simple baffle to minimize this.

Im at 4100 kms as of last night and will look into the tank by next week to see how effective or not it works.

I plan on doing intake, intercooler and exhaust upgrades as well as putting an AEM water/meth system to see how much I could push the stock turbo+engine+fuel system combo to keep it as reliable as I can. Unfortunately, shop/work hours dictate that I / we couldn't give much attention to this car but hopefully soon I'll be able to do all of these within 2-3 days and do some dyno tuning again.

I'll update this thread soon after a couple of mods and hopefully with dyno graphs along the way

PS: Sorry for the watermarks on some of the pics. I recycled them through our fb page and didn't keep the original ones

Very cool. Very professional fabrication. You could probably sell those pretty easily.
What king of mpg do you get with out the emissions stuff ? It has to be better than our US models with all of that stuff. We get great mpg's but I bet you get better.

Nicely modified truck. I also did a catch can after finding oil in my turbo.
I really like that body style. It looks much more aerodynamic and should increase mpg's by a mile or two.
Interested in this guys findings. Stock without the emissions BS would be ideal, and what Im sure most of us will go for eventually. @Profab Chino , any update?
