I installed a new Precision Turbo 44 with an ATR downpipe and wastegate. My truck charges hard and quickly from 8 to 16 pounds of boost but is sufferring on the bottom end. Even on the brake I can't seem to get any boost to come up and when I do launch it's a dud! Anyone have any suggestions?

I have the same set-up. I have the Pte-44, Wastegate, and 3" ATR downpipe. I also have a 2800 stall though and can get any amount of boost I need though. I usually take it up to about 7-10 psi

Re: Help w/ new turbo

and why am I going to blow my engine. I'm not overboosting, I'm underboosting. This is the same chip that has been in the truck since 1993, I'm sure it needs to be updated but as for now the slow boost is my main concern.

Re: Help w/ new turbo

high octane tune + no knock retard on "streetmaster" = kaboom

if you only run 118 octane then you'll be fine.

Why:

Kenne Bell chip the way i understand it disables the knock sensor or minimizes to something like 2 degrees max. Something along those lines. Basically, if you are getting knock you'll never know it and your motor will go.

Did you use the copper gaskets that go between the wg and the dp? If so they could be missaligned and not letting the wg close all the way. And get rid of the kaboom chip.

I did use the gasket but will check tonight for misalignment. Thanks, and for the chip, it looks like an ultimate is probably the best choice. Is rpm the only place to buy because I checked sytychips website and it said they where pursuing other ventures at this time. Thanks.

Re: Help w/ new turbo

Thanks Maverick87, the gasket was in a bind and the wastegate valve was imprinting the bottom edge of the gasket, with proper alignment I was able to boost about 4psi and boost was smooth up to 15. G-tech showed a 1.76 60FT. and a 3.98 0-60.and is very accurate as it was tuned @ the track with multiple passes about a month ago. Once again thanks for your help. Lee

Re: Help w/ new turbo

jwaller, no , actually I bought my sy brand new from Jim Hudson. I have put every mile on it except the 7 it had when I bought it. I think you are in Lexington from what I am reading on some of the posts on this site, if so stop in sometimes at Ace Glass on #1, I am the manager there, you've probably seen my blue silverado sitting out front.
