Hey, I bought a 98 r32gtst a month ago as it drives like a new car beautiful tight shifting no dents at all perfect original interior everything is still rigid good smooth motor. It has a front mount, podfilter, 3.5inch catback, per4manz highflow turbo from perth a while ago with garret guts and bush bearings, it reads 15 psi full boost. The only thing im a bit worried about is that it isnt tuned at all!!!!! it runs smooth and everything but exhausts some black smoke when i spool it so i guess its rich, but its not tuned??? i thougt it would run lean with a turbo upgrade.. plus its real laggy do you think thats because of the stock down pipe + non ball bearing turb + plus big intercooler + rb20 ? the other question would a tune make it spool earlier? it pulls at 4.5k i raced a standard r33 the other day and it only just beat me would a tune make it less laggy and alot faster? coz it still lost to a standard 33 with all my upgardes...? cheers
