RECENTLY BOUGHT 87 GN ALL STOCK. I HAD TO CONVERT TO VACUUM BRAKES POWER MASTER FAILED. RECENTLY TUNED, OIL CHANGE, MAF CHANGE OUT, K&N AIR FILTER, PVC CHANGE OUT. NOT SURE HOW ITS SUPPOSE TO RESPOND. SITTING STILL I HAVE TRIED TO BURN THE TIRES BUT I JUST LAUNCH. DONT HAVE MUCH MONEY TO INVEST AT THIS TIME BUT WANT TO TRY AND MAKE IT FAST. THE BOOST GAUGE ON THE DASH SEEMS TO TAKE AWHILE TO BUILD UP AFTER TAKE OFF. I AM NOT SURE WHAT TO LOOK FOR TO SEE IF THERE IS SOMETHING WRONG. ANY HELP WOULD BE APPRECIATED.
