Getting an 01 from a friend and selling my 97. I'm swapping on my TS chip, Wildman tunes, and Wicked Wheel 2.
My buddy has a DP Tuner on it with an adjustable regulator as a boost fooler. Couple questions:
What PSI should I set the boost fooler to?
Is there any needed mods or adjustments to the wastegate? My OBS doesn;t have one...
And lastly, what boost PSI should I limit the truck to so I don't frag the turbo?
Congrats on the new truck! Now lets see some pics!!!!!
First, i am not sure your TS chip will work correctly with your PCM, you may have to send it in to get reburned, this would also benefit you because the 01 will have slightly bigger injectors, bigger HPOP, bigger inter cooler and the turbo a bit different. Getting tunes for the upgraded parts compared the 97 will help quite a bit. At this point you could go with any of the tuners (except DP), i like my PHP tunes. Have not tried any others.
Second, i would be a bit Leary of the boost fooler he has on there if it really is just a adjustable regulator. Read the link i posted. PHP tunes also do not require you to have a boost fooler, the SES light will still trip over 25 LBS but the motor will not de-fuel.
There is a Turbo Master Wastegate that people like. My truck came with a Bank Big head wastegate and it is hardly better than stock if at all. The wastegate weather it be stock or aftermarket can be adjustable by turning the actuator arm, tightening it, this will keep the wastegate closed a bit longer helping create more boost.
Most sites say do not go over 32 PSI with a stock turbo for long periods of time, with the new billet wheels they have available i would run my turbo at 32 PSI all day long, the drive pressure to back pressure are pretty darn equal with the new wheels. When the 2 are different is when you start creating excessive wear and tear on the internal parts.
Good luck with the truck! I love mine and dont ever see myself getting rid of it. Upgrading these things is very addicting!
