What kind of tuning do you need to do? I use a scanmaster 2.1 and a EGT unit like RJC sells . I have one of Eric's chips so that's all I realy need. I added some fuel when I went to 23lbs of boost and I set my Razor Alky at 6.5 #s go like this 777 0.0 @ 23-25lbs. That's with a 6262BB, PTC SLIC, ATR SSDP, ATR SS headers , little Comp cam very little head work, stock 109 ,3in Cottons exh , PTC2800 and Richard Clark and I built the tranny. Richard helped me alot when I first got my car. It was a 1 owner stock 87 GN with a fresh motor none by Steve V. The tranny was also fresh but we made it a lot stronger. I have cut a few LS1s and 1 LT1 with 2 stages of NOS. I just got new Micky T 275/50/15 last week but I still can't leave with any boost over 2/3lbs. Razor installed my alky at Richards shop so we did a little dyno tuning whil we were there. All the other parts I installed and tuned myself. The only thing on the car when we done the dyno pulls was the alky and a TA49 stock DP and headers. Like I said it was a stock car before I started with it . All mods were done by me other than the alky. It more fun than my old 70 Nova drag car that was running 6.30s . The GN is slower but not by much ????
