Hi, I made a couple passes today and the car continues to runs lean at wot. I had to lift before the 8th with EGTs at 1725 and climbing. I've been dealing with this lean condtion for a while now. I've replaced the pump and have installed a gen II translator and a TT 5.7 chip do to the stock...

Will a chip with forced tc lock up work ok with a N/L converter? I think so but want be sure. Thanks, Don

I have 2- 009 race chips, $30 each shipped: Reds 107 - I think this is a 24* chip with forced TQ lock-up Turbotweak - 24*timing WOT in all gears with fast update for scanmaster and forced torque converter lockup at 80 MPH. This chip worked great with 110 gas or 93 and alcohol. If you...

My transmission shifts ok from 1st to second but then almost immediately into third. This is only at part throttle. WOT shifts are fine. I have been putting up with this for a while. Lately I have spending more time on the street than at the track so it's getting annoying. I have readjusted...

Greetings All, I plan on replacing the trans yoke with a forged one. Twisted splines in the second stock one. :D Which series universal joints are used in the stock drive shaft 1310 or 1350? Thanks, Don

Will the 8-1/2 “ carrier from a 91 to 95 Caprice work in the GN rear? I think they are 30- spline so the axles will need to be changed. The Caprice has ABS sensor on the pinion, but I wonder if the carrier is the same. Thanks, Don

The ESC on an 86 is a different part number than on an 87. Is there any difference (like the way it interprets knock or the amount of spark pull back)? Also will they interchange? Thanks, Don

When changing transmission what is the best method to clean out the transmission coolers and lines? I have blown them out with compressed air, but should I use some type of solvent as well? If so what type of solvent works best and won't harm the flex hoses? Thanks, Don

A few weeks back I ripped about 1/3 of the teeth off the ring gear. It happened on a 20# launch with 9 X 28 slicks. The gears were fairly new they only had about 500 street miles and 30 passes on them. I set them up to specs (kept the backlash on the tight side), the pattern looked good and they...

My transmission occasionally won’t shift into 3rd gear at WOT. It happened one time last year, then again once last night. It has only happened twice in over 100 passes. Once I lift the throttle it shifts. The transmission is a stock 2004r with a B&M shift kit. I haven’t adjusted the throttle...

I haven’t read many complaints about this but … the D5 in my car will build more than 15# of boost on the line with the foot brake. The car leaves real hard and the MPH seems about right. My concern… is the converter about to break? Or am I just lucky? :D Don

My MPH seems a little low: 1.65 - 60’ 7.57 @ 90.11 in the 1/8 11.89 @ 113.8 in the 1/4 The converter is locked at 80 and the motor was turning ~ 4700 thru the traps The EGTs were 1642 (I have the FP up to 52 line off, at 44 the EGTs were 1700 +) This was on a 24* chip and 25 # of boost...

I finally took the heads off to replace the head gaskets. I noticed the pistons had 3 notches to the front and they are .040 over. I checked gnttype.org and they show all turbo pistons with 2 notches. I sure hope they aren’t N/A pistons. Thanks, Don

Coolant pushed from radiator into overflow tank during high boost (25psi) runs. I figured I must have blown a head gasket. Before I pull the motor I did a compression and leak down test. The compression is between 168 # and 172 # and the leak down was about 18% in all cylinders. During...

Are SPS head bolts re-usable or are they TTY? It's head gasket time:D Thanks, Don

My time is up; I have to get the Buick through emissions. I have re-installed the cat, put a street chip in (RA93) and set the boost back to 15# max. I have also changed the o2 sensor since running race gas. The blms are kinda low at 116, should I lower the fuel pressure from 43 to about...

What is the optimal boost range for a TA-49? Is 25-26 too much?:D (stock unported heads and open exhaust) Thanks, Don

I would like to set my scanmaster so I can watch other modes (like AF, rpm, pl or sp) while making a run. Will it still record the lowest o2 mv and highest knock retard while set in the other modes? Thanks, Don
