Okay guys, Here is what happened to me, I blew an oil seal out of my TE-44 about three weeks ago, it was oil coming out if the space between the exhaust turbine and the DP running down to my wastegate flapper and dripping on the lower radiator hose. In other words, it was oil every freaking...

Hello boosted friends, Well, after many adjustments on the streets and three failed track visits attempts (rain), it was time to take advantage of some free dyno time. My car has: a TE-44 (23psi)/Dutt neck/3"THDP with dump/MSD 50psi/340 with hot wire/TT race chip/ATR true dual 2.5...

First, let me thank TurboDave, Bison, VadersV6, RUQWKNF and Pacecarta…you guys helped realize that I was not crazy and that one cannot always follow conventional wisdom when it comes to tuning these GN’s. I started my GN life with a simple original 26,450 miles almost 100% stock example, and...

Hello guys, I've been playing with my car for these last 2.5 weeks trying to find her sweet spot on pump gas before heading out to the track (it's tough for me due to work). So I'm doing much of my tuining late at night on empty streets late at night, and here is what I got: For some...

Hello guys, Can I please get your input on this matter: Fuel pressure...when do you typically adjust your fuel pressure? I'm asking because I thought I had this matter pretty much resolved until I saw the fuel pressure go down once I drove for a while. The car felt a little flatter...

Folks with knowledge from a similar set up, please give me your take on the below script. I am in the process of fine tuning my combination; I ran through the sequences of the adjustable parameters from 1 through 4 as indicated on the TT chip literature, and discovered that the number 4...

Hello folks, I am new to this forum, and new to this whole GN family. After reading and speaking to a few of you through PM’s and the open forum, I went ahead and decided to upgrade my set up. I noticed on the parts section that Mr. Brer Rabbit from Chicago was selling a TE-44, we spoke...

Hello all, Can some one please tell me if it is possible to have both a TT chip combined with a T+? I like the flexibility of the T+. Meaning, if you get a dose of bad gas, then just turn down the fuel and timing dials. But if you decide to throw in some racing gas, then you can turn up...

Hello fellow boosters, I am in the process of making a quick decision and I need some help. I has been hard to find a decently priced DP new or used. However, I just noticed that Poston Enterprises sells their own in-house 3" DP's that is a two piece that comes complete with clamps. My...

Hello guys, I recieved my new TT chip the other day but have not installed it yet. After reading the instruction, it came to my attention that: 1) I better get my header leak fix first. 2) I may have to hire someone to do it for me since I don't own a scan tool or scanner 2.1, and...

I have a header leak on the driver side. I can hear it when the car idles while warming up, when driving down the road when I mash the gas. When I'm under the hood it sounds like a ticking/spit sound, I thought it was the rockers, but nah...they are all nice and tight. It's driving me nuts...

Hello Guys, Saturday I had the GN dyno'd just to see what she is putting out, and here is what I got: 246/308 to the tires. We pulled it three times, and three pulls were about the same, A/F was about 12.7 or so while boost sat steady at 15 to 16psi. We all know that in '87 all GN's...

Hello Guys, I need your help again...changed oil & oil filter (PF52) for the first time with Mobil 1 synthetic 10W/30. I added 5 qts of oil and now 24 hrs. later the dipstick reads about a qt low. I called the local parts store and was told that Grand Nationals take 4 qts with filter. Is...

Okay guys, I need your help again, what is your typical speed secret/formula/recipe for making a typical GN run high to mid 12's on STREET tires (no DR's and no slicks) on PUMP 93 octane gas? I WANT TO BE ABLE TO RUN HIGH TO MID 12'S ON STREET TIRES AND 93 PUMP GAS!!!: To save you some...

Hello folks, I am a first time GN owner and I need some help. Ideally, what amount of timing do you guys typically run on pump gas with 16 to 18 psi in low gears and high gear? And the same goes for fuel psi. FYI, I have the T+ and extender chip which gives control of timing base/wot and...

Hello fellow boosters, I am in the market for a nice but NOT too expensive Cold Air kit for a 87 GN. The car currently have a LS1 MAF sensor, otherwise everything else is stock. Thanks in advance for all your help:smile:
