Kit Vexed Posted April 3, 2009 Report Share Posted April 3, 2009 i installed the delco tcv and its adjoining plug yesterday on my T-5R... shiny nipple goes to turbo, filtered nipple goes to the intake, and the last nipple goes to the wastegate. the nipples on the new delco solenoid are smaller in diameter than the stockers, so you gotta basically zip tie them tight onto the delco apparatus. that being said, what's the problem? sound like i did what i had to? car isn't throwing any CELs or anything... i also did the correct 'learning' procedure where im driving normal for about 10 miles, then i full boost it for 3 secs, then normal again. the first time i full boosted after the install, the car spiked up to like 17psi, whilst i have the iPd stage I tune of 15psi. i was thinking, 'whoa' lol. thereafter, it never full boosted (even to normal of 15psi). i know i hooked that thing up right... could i have blown a hole in my CBV with that little spike the first time? NEvER had a problem holding boost until i installed the delco tcv... from a stand still, i could pin the pedal, and it'd almost immediately boost to 15psi and lose all kinds of traction... now, i pin it from a stand still and it's only boosting to 10psi and losing no traction??? what gives?

dongle Posted April 3, 2009 Report Share Posted April 3, 2009 I noticed this too. I don't have a guage in the car right now, but Im still not convince that the Delco is an improvement over the stock unit.Tested them back to back.

Dave 54 Posted April 3, 2009 Report Share Posted April 3, 2009 I've been waiting to install mine for this reason, wanted feed back. Think there's something to IPD's not working on 850's w/BCS as well as the AC units. Lucky I believe touched on this In the GB thread as to why there's is not compatible with BCS style. Anyone else having issues. Link to comment Share on other sites More sharing options...

Dave 54 Posted April 3, 2009 Report Share Posted April 3, 2009 I'd say do a leak down, fix all leaks and go from there. I know I am leaking bad as I have 17psi tune and only able to muster 12.5-13 with a spike to 17-18 at shifts Link to comment Share on other sites More sharing options...
NEU Posted April 3, 2009 Report Share Posted April 3, 2009 I've got the opposite results, I get boost spike of 18psi at WOT, but it normally runs around 14.7psi and I've got ME7 ECU. Link to comment Share on other sites More sharing options...
Kit Vexed Posted April 3, 2009 Author Report Share Posted April 3, 2009 i'd read that the delco tcv was an upgrade, so i figured id do it... crapppy part about it is, i spliced and soldered the stock wiring and delco plug... wtf? Link to comment Share on other sites More sharing options...
Dave 54 Posted April 3, 2009 Report Share Posted April 3, 2009 That blows, ya I inquired back when lucky was running the GB for them and was in until he said they had seen issues on BCS, and would only offer it for non BCS. So when everyone was getting wrapped up in these for the non BCS I was wondering how they are working, and if anyone is expierencing the same issues IPD saw in there BCS testing coming up.

Kit Vexed Posted April 3, 2009 Author Report Share Posted April 3, 2009 well, i still have my stock solenoid, so i guess i'll just have to splice and solder it back in, lol. arrgggg. so i guess i have a delco tcv and pigtail for sale... anyone interested??? $60 shipped... i paid $42 for the tcv on gmpartsdirect, and $23 for the pigtail @ a local dealer. PM me (but remember, i still have to get it off the car which my take a min cause the weather is rain rain rain here in CT). Link to comment Share on other sites More sharing options...
mark_850t Posted April 7, 2009 Report Share Posted April 7, 2009 You need to break in the tcv correctly. Did you install with the battery disconnected like you are supposed to? The ac delco TCV is much, much better than the stock BCS, boost builds much quicker and boost holds better. You install it with the battery disconnected... when you have it all installed, drive without going into boost for about 5 to 10 miles. Then do a couple decent pulls and drive the car normally for a bit, turn the car off and start it back up. When I installed the new AC Delco tcv I didn't notice much at first, and was disappointed. But after about 10 minutes or so the car was way more responsive to throttle and the turbo much faster to spool. It now spools to 14-15psi in about 1-2 seconds. It is a great mod when done right.

Guest Guest_simonvexed_* Posted April 8, 2009 Report Share Posted April 8, 2009 i did install it right, as said in the original post... as far as disconnecting the battery - of course! who doesn't need the space? and just as a rule of thumb i always disconnect the battery when doing anthing with the sensors/electronic tid bits... maybe i do have a leak since the new delco piece has smaller diametered nipples? but i zip tied them tight as i could and i have the stylin kit to boot..

CO.T5M Posted April 8, 2009 Report Share Posted April 8, 2009 i have the Acdelco on my car not its fixed all my problems and it boosts the stock Psi great and really is keeping the car power levels where i want them Link to comment Share on other sites More sharing options...

Did you make sure the polarity of the wires was correct? I know you prob disconnected the battery but I was just checking. I also am running a blanking plate on my 15G in accordance with my BOV, so perhaps there is a leak in the cbv or something? Sucks when this type of stuff happens, I was lucky mine went off without a hitch. Link to comment Share on other sites More sharing options...
