Gearhead SRL tune- first time use
So.....I installed my first ever "custom tune" on this truck yesterday. I hadn't even been running the canned SCT tunes. I just went straight to a custom tune.
Anyway, here's what I've done to the truck (it ain't much):
1. 4" turbo back exhaust with muffler and 4" down pipe
2. PHP Atlas-40 FICM tune
3. blue spring mod
4. ScanGauge-2 and 3-in-1 Glowshift gauge
5. Coolant filter
Intake, EGR, head bolts are all still stock.
I went to Matt @ Gearhead and got his package of 3 tunes (SRL, 8kTow and Unlimited Tow). I ordered them Wednesday and got them Thursday. Now that's service!
I wanted the full monty so I went right with the SRL tune and installed that during my lunch hour. I started the truck up but found that my ScanGauge-2 wasn't reading any of the extended PID's now. I didn't have much time to troubleshoot so I turned the truck off. After work, I started the truck up and again noticed the ScanGauge wasn't working right. I unplugged it and plugged it back in but no joy. I turned the truck off and restarted it and again no joy with the ScanGauge. With no time to troubleshoot I headed to the grocery store. When I came back out and started the truck up the ScanGauge was now reading correctly. I have NOOOOO idea why it did what it did after I installed the Tune but I have read of one or two other people that had the same issue.
Anyway, while pulling out of Safeway I decided to check out the tail pipe smoke and got on it just a little bit. There was no smoke. I thought "hmmmm....I'll just get on it hard and then see how much it smokes". Well, it scared the **** out of me because I was not expecting it to take off like a bat out of hell. And when someone said that it changes the sound of the truck, oh hell yeah it does. That thing got mean and nasty sounding like it was eating up small children for lunch. I looked up and saw my EGT's climbing really fast so I let off at 55mph and checked the rear view mirror. There was some dark brown smoke but nothing like rolling coal. I was now extremely impressed.
Here's what I noticed on my 22 mile drive back from the grocery store:
- It's now waaaaaaaaay faster than with just a 4" turbo back exhaust and FICM tune.
- The truck is more responsive on take off and just driving around town.
- The EGT's climb really fast so I'll have to be keeping an eye on them when I get on it hard.
- During normal easy driving and highway cruising the EGT's are actually lower. I expected them to be higher. The same mile-long hill just before the exit to my town, I would hit 780-800* with the FICM tune and 4" exhaust. Now it's hitting 700-720*. I'm not quite sure why that is especially if I'm running the hotter tune.
- During normal driving the truck sounds the same. Get on it hard and holy moly it snarls.
- I may look look into a water injection system just to help with the EGT's.
And, from here on out I gotta be careful and start planning for the inevitable headstud/headgasket repairs.
