This past week I finished up installing my new QSSB turbo kit from Wide Open.
Mostly I needed to do something about my turbo system since the uppipes were leaking so badly, that when I pulled the collector and uppipes out as one unit, one uppipe just slide out of the collector.
Unfortunately when I took everything apart, my uppipe bolts were so rusted there was absolutely no way to get them out except cut them, which meant the manifolds needed to come out, which were also so rusted the shop that did them had to cut all the bolts and weld on nuts to the studs and get them out that way. It was quite a mess. They ended up replacing the oil cooler too because that was so rusted it was almost ready to go.
Anyway, I finished up the install. Over all the EGTs are much lower, runs at about 700 on the highway, and I haven't got it over 1000-1100 yet. Seems the EGTs just climb very very slowly. Runs at about 4-5psi cruising on the highway.
Also the turbo has a nice linear pull to it when the boost is up. My stock turbo was surging uncontrollably, to the point I could just barely roll in it on the highway and it would surge.
I can't get this turbo to surge at all, which makes driving very nice.
I do however have two noticeable issues.....
For one my mileage has taken a nose dive. I'm burning a lot more fuel than my stock turbo with leaking up pipes. This makes no sense to me at all, it seems I should have gotten a little better mileage, no idea why this is happening.
And second the truck has a little "lurch" at about 1700-1800RPM, almost as if the peddle was stuck or it was not getting enough fuel up until this point. Even it my stock tune it does this.
Do you guys think getting new tunes to match the turbo would solve these issues??
I really can't see how bolting on a new turbo that flows a lot more air would have HURT my mileage
