Hey everyone how's it going? Basic question here, I have some light mods done to my 89 Iroc. Headers, AS&M large tube runners, ported stock tpi base and plenum, mild cam. Can runs good, but it's on a stock tune. Just curious if the mods I have are enough to warrant spending the money for a custom tune? I don't know a whole lot about tuning, so any help is appreciated. Thanks.

 

A good tune will net you big gains at this point.

 

Any recommendations on who I should contact?

 

No, I definitely have never looked into a tuner as I do it myself.
Best is to find somebody to do it in person or at least over many datalogs.

 

Call TPIS, tuned port induction specialties, ask for Jim. he can help..
