Picked up the Sy a last sunday and everythings is good. I needed gas so i went to Shell to fill up (usually use Chevron) .. after topping off with 91 i went for a cruise. After about 15 miles or so .. when i get into boost after 7 or 8 psi it knocks and retards timing/boost.
I got a bottle of NoS offroad octane booster .. helped the knock problem. but now there might be another problem.
Didnt get to do the scan tool .. Knock has pretty much stopped (was the gas) but was troubleshooting the lack of accelartion problem last night. I dunno but it seems like the trans is slipping.
When going from a stop and if i get on it almost seems like the trans short shifts to 2nd at around 4g. Boost feels fine when accelrating from a dead stop, its only in The higher rpm's it slows down and feels like im not boosting anymore. The stock boost gauge dosent drop below 12psi. But when going 60 - 65mph speeds and if i get on it it the trans kicks down to 3rd and momentaraly boost kicks in and the gauge (stock) goes to 15psi, then it pulls and shortly after i get some pretty good vibes accelaration is slow and the rpm is climbing really slow 3000rpm, 3100rpm, 3200rpm, all while boost dosent drop much maybe 10 - 14psi. I dont think that its the motor or turbo because when i let go of the gas it releases the pressure (Psssst sound). If i accelarate with half pedal it pulls fine, i stay in boost 12-14 and accelrates damn good for only half pedal ... its only when i go wOT. it does it. This sux :rant:
What do you think? Is it the tranny or motor?
Im gonna have a mechanic friend of mine troubleshoot it and get a second opinion .. if worst comes to worst I can have the trans beefed up and rebuilt with a 2800 converter. (or if anyone can suggest a good combo)
Thanx
