Turbo Tweak Chip 5.6 Adjustable?

[Franks86gn]

I have a TT 5.6 chip that has this written on it

TT 5.6 6121
55# STREET 93
20`-18` 16-18psi

I do have 55# injectors and I understand everything except the "6121" Any ideas?

I know that some older TT chips are not adjustable. Is the 5.6 adjustable? If so, are there any instructions available online?

TIA

Yes, the 5.6 is adjustable. The 6121 is the original order#.

Here is a link to the instructions: http://www.turbotweak.com/turbotweakinstructions56.pdf

Thanks Eric. Is there any additional info you could relay to me on that order number? Like cam, turbo, ?

It was made for a car with stock heads, stock cam, and a TE63 turbo. It will probably be a bit lean for your car depending on boost level. Might need another 10% WOT fuel or so.

Thanks a lot! I have stock heads but a 204/214 flat tappet camshaft, champion stock ported intake, gt6776e turbo, still need 10% more roughly? Just an idea. I plan on first drag strip tuning next week and would be cool to have a general idea after a baseline run.
