Please help! I'm not sure if this is fuel cut or what, but it sux and is very frustrating.
I've done a bunch of things to my msp such as:
manual boost control, front mount intercooler (from a DSM starion), custom stainless intercooler piping, cold air intake (straight to the turbo), blitz SS BOV, fuel pressure regulator, custom stainless exhaust, high flow catty, apex-i n-1 muff),i ain't gloatin, juss for info incase they have any bearing on the problem i'm experiencing.
1. I've heard some peeps say that there is no fuel cut on the msp, but I found that when i had my boost up to 10+ psi, and punched the throttle, the flow was being cut off abruptly. On my A/F guage, it would show rich when the boost was spiking and then instantly go to lean when the boost held steady for about 1 second. is this fuel cut? has anyone had a similar problem? how did you deal with it? if it is a fuel cut, how do i get around this, or does anyone know what senses the boost being too high and cutting off the flow.
2. when my boost is turned up to about 10 psi, and i have the throttle about less than half pressed, my car gets this horrible stutter when it gets around 10 psi. my A/F gauge reads rich and then goes to stoich/lean, than back to rich repeatedly. anyone know what this is?
3. If fuel management is the answer to these problems, what have you done? piggy back (what kind) or stand alone (what kind)? even if fuel management isn't the answer to this problem, i'd like feed back on fuel management alternatives because i'll be replacing it this winter.
Sheeit! i didn't mean for this question to be so long, but this problem has haunted me all summer, any info/tips greatly appreciated.
p.s. i was running my boost at 12-13 psi after i got my new intercooler a month ago and within a week i fried my turbo. still works a little, but tails off badly under high rpm (spikes at 10, leaks down to about 6), plus it sounds like a little girl screaming (jokes) when boosting. the turbine is extremely loose. anyway, learn from my impatience/stupidity: don't go crazy with the t-25.
