MAFT Problems

[awdwhip]

i have about the same problem as the guy 91-gsx . here is a list of mods. 650's, walbro 255hp, safc-II, MAF Tranlator, no filter for now. the boost spikes to 19 and sets to 15 psi. 3inch turboback no cat with n-1 muffler. t-25 turbo. at aorund 4 grand the engine just stumbles and cuts boost. ive tried leaning it out and richening it up with no progress. could you guys help me out? thanx.

1. do you have an AFPR
2. have you checked for any boost leaks
3. Which are you using to tune with your SAFC or the maft
4. Have you tried changing the plugs and or wires
Have you checked your logs to see if your knocking or showing signs of knocking
but as far as boost falling off t25 cant keep up

hey we do have the same problem but you can get rid of yours becuase the safc has a switch i believe for a fuel cut defencer, use it and you will not cut anymore.
good luck... to the both us.

Howmuch boost are you trying to run? likely in your case the stock BOV is probably failing as they cannot hold much and they open. A 1g BOV should solve it. Mark
