TW & A Funny Shiftin' Tranny

[RadarRider]

I'm still @ the extensive testing stage of the TW chip & it's great! My only concerns are with 'stock' & 'daily'. Before I start, let me just tell you driving conditions of Rhode Island to make sure this isn't the chip's fault. I know daily is used for driving around town & also great on the highway. The thing about RI is, there aren't too many roads where the speed limits reach past 45-50mph & also don't go for miles & miles. Most of the roads are short & windy & mostly have speed limits of 35-40mph(40 is almost a rareity!). My problem is, on the 35-40mph roads, I'll give it 1/4 throttle & it will shift early into 3rd & rarely 4th. If I have to let off, depending on how fast I'm going, & get back on it, it'll upshift early & I can hear the wastegate open. BUT: if I go on an onramp for the highway & give it 1/2+ throttle, it'll shift nice & smooth & I'll have plenty of power! Another thing is: if I try this on a main road, by the time I get to O/D I'll be doing 50+mph. It seems it'll only shift smooth when I give it 1/2 throttle on main roads with a 50mph speed limit. Also: in stock, if I give it 1/4, it'll hold out 2nd & thud into 3rd(w/ wastegate opening). Just like daily, I'll still have power, but not sure if it's supposed to do this. As far as I can see with the stock problem, I don't think it's the TW's fault. I think it's because of the lack of tranny settings, & the fact that the turbo modifications probably mess with the stock shift settings.

The shifting in 2nd or Tow is good and so is 4th Street? Or which one do you like betterf (shifting)?

Wastegate is a boost controller. It only opens when it reaches your set pressure. What your hearing is surge or just the release of the pressure back through the turbo. I've been reading alot of people saying that they hear their wastegate opening lately when that is not the case.

I just wanted to clear that up. As far as your other issue I don't know.

^How true....you can't hear your wastegate....


That being said, I would PM your OP to Tony and see what he says. He'll be able to help you better than any of us....He knows how your truck was tuned.
